- Why are prime numbers important? Are there any practical uses of prime numbers or are they taught in school life just for covering academic syllabus! Get familiar with some practical uses of prime numbers in this short animated video.
What is so weird about prime numbers?
What is the use of prime numbers in real life?
Do share with us if you know any more real life uses of prime numbers. And what do you think about periodical cicadas, using prime numbers for their existence. Isn't it just amazing. Keep watching for more such curious Tell me why shorts every Monday @ 5PM (IST)

When you say "congratulations, now you know...", i feel like there should be an achievement sound or something.
heres why they are important : prime numbers are the building block for all the other numbers.... one of the very important use is prime factorization is data encryption .. which gives us a kind of "one way" encryption. For example it only lets us convert from (a) to (b) not (b) to (a). Its kind of because its not really a 1 way... realistically it is not 1 way, we can always find the prime factors of some number it just might take a VERY long time depending on the size of the number and in encryption the numbers are HUGEEe. But if we were to find a formula for generating primes.. it would be significantly easier for us to check up to say the millionth prime number with a simple loop than check all possible factors of a number thus at that point the encryption system becomes too weak but (un)fortunately we dont have a formula to generate prime numbers. Prime numbers are also important in many branches of math as it is literally the building blocks of all real numbers.
Funfact: if you could solve the collatz conjecture that will help with understanding prime factorization.
But *how* & *why* are they the building blocks of other numbers!?
@@gnarlynicholasreviews take anу number that is not a prime, and уou can decompose that number as a multiplication of primes. for example 6 can be expressed as (2x3) or 396 could be expressed as (2^2 × 3^2 × 11). remember that 1 is not a prime number because of this reason as it would lead to decomposition's looking like this ,10 = (5x2x1x1x1x1x1x1x1.....) with infinite possible 1s in its decomposition so for simplicitу we saу its not.
Question is unanswered "Why are prime numbers important"?
He doesn't have to answer it. He just has to explain the prime numbers.
@@jessehu1061 How do you explain oxygen without its functions in human body?
@@jessehu1061how dumb can u be homie 😂
I don't know the intended audience for this. But I am pretty sure this kind of explanation can be found in a decent book.
This video:
"2 + 2 equals 4. This is important because every 4 years we have a leap year. unless the year can be evenly divided by 100, except if the year can be divided by 400. Notice how 4 x 100 = 400. Also 400 - 100 = 300, like the famous movie. So now you know!"
I'm most likely asking for the moon here but I understand why prime numbers are a thing but not the main reason why we are chasing them. There's just examples here of primes and not a true explanation of what's so incredibly important about them and what equation for them could be used for.
They defy order and sequence ....They seem to dont fit in to our number system they way other no.s do
So if you’re a cicada or a turbine engine, prime numbers have an obvious importance. Other than that, it’s just something for geeks to ponder.
Thank you. I'll solve Riemann's hypothesis now
Thank you bro. I've heard this saying: "May not God lead all the universe. But there's something odd with Prime Numbers" so i wanted to check for that. From your 2 minute video, I've been able to figure it out what that saying said.... Dude, you're amazing....
Thanks for the video. Does anyone have other examples from nature where primes are used?
casuality is not causality, so cicada happens to match prime numbers, wooohooo now you know the importance of prime numbers
Write a detailed report explaining the importance of prime numbers within the field of computing by using practical example of application of prime. Cheers
At the middle of this video I decided to see comments and having viewed few comments I pressed the back button to for others video.
Wow that made no sense to me. Why would cicadas have anything to do with prime numbers to me this looks like magical thinking.
Very good! I learned something new!
Why are prime numbers important
TELL ME WHY
AIINT NOTHIN BUT A HEART ACHE
TELL ME WHY
Lmao at congratulations
Nice

It's not answered my question prime numbers are thousands of years old
nice vid as usual
1:28 - 1:40
i may be derp but i dont understand why 59 is better than 60 in that example (let alone how the blade number in general is related to vibration, rotation or anything else u said for that matter xD)
even after carefully examining the visuals :(
I wonder how can you be a creative ninja in every field- computers, biology, botany, philosophy, economics, astronomy, technology etc.
PS I also a mechanical engineer. :)
what is a popultion cycle? lol great vid
The video was very informative, fascinating. It was very well made too :)
Still…. Doesn’t really explain why everyone needs to learn them at school. Lol
Watt arr prrime namberrs imporrrtant?
You tell us, Scientist Albert Einstein
Ummm, I get why they're important now (that cicadas thing has totally blown my mind) but I still dont get how to work it what is a prime number.... Can't everything be multiplied by one? Can't everything be multiplied by its own value? Can't any number be multiplied by any number?
*****
Yay!! Examples!!
>>>> 69
Ohhhhh, I think I gotcha now!?!?! So there are NO two numbers you can multiply to get exactly 67....?

Ummm, composite number is a new term :/
Gringo Show a composite number is just a number that's not prime. a prime number only has one prime factor and 1.
The reason is because for any prime number, it is cyclic when compared to any other number.
If any two numbers are relatively prime, they are cyclic, as in, they pass through every iteration of number in it's modulus. Take two non relatively prime numbers, 2 and 6. 2 in modulus 6 generates {2,4,6,8,10,12,...}
The way mod 6 works is that for any number greater than 6, we divide it by 6 and look at it's remainder, so 10 is just a remainder of 4, so we say 10=4. and 11=5, 12=6, 13=1, and so on.So 2 in mod 6 only generates {2,4,6}.
Two numbers that are relatively prime if they share no common factors. So 6 is 2x3 and 2 is 2x1, so they share 2 and are not relatively prime. Note, any prime number is relatively prime to all numbers, for obvious reasons. Now let's take two relatively prime numbers, 9 and 14, note both are not prime, but let's look at how 9 cycles through in mod 14. It looks like this {9,18,27,36,45,54,63,72,81,90}, so this is actually {9,4,13,8,3,12,7,2,11,6,1,10,5,14}. As you can see it cycles through EVERY number of 14, so what you end up taking out of this, is that 9 and 14 end up lying on the same number every 14 cycles, the maximum number of cycles.
Now for the cicadas, since their population cycle is prime, that means their population cycle is RELATIVELY prime to all other cycles, always giving the maximum cycle time to be matched with predators.
To reset the universe
what
Ahhh ok. I still don't get it.
so no one really knows why they are important.
exactly
Not understand please explain clearly application
What?
This did nothing for me
What a waste of time.

Wtf why are you talking about cicadas?
its a coincidence that cicadas emerge from the ground from 13-17 years underground you ungrateful bitch.
Ok. So this didn't explain anything
Actually it did. The most basic explanation is that if you don't want cycles of things to coincide, primes are best for this since they have only two factors.
What a waste of a video. Keep yourself safe
