Learn Greatest Common Factor (GCF) & Least Common Multiple (LCM) - [7]

Twitter: / jasongibsonmath
In this lesson, we will learn how to find the greatest common factor (gcf) and least common multiple (lcm) of two numbers. These ideas are important when working with fractions, finding common denominators to add fractions, and other operations with fractions and numbers. The GCF is found by finding the factors of numbers and looking to find the largest (greatest) factor common between two numbers. Factors are simply numbers that can be divided into a number. To find the least common multiple, we just find the multiples of the given numbers and look for the smallest (least) multiple common to both lists.

Mr. Jason Gibson is an excellent math teacher. He has a way to explain things that, as long as youare willing to learn math (as opposed to be hostile to math), his teaching is easy to follow. He is never vague or intimidating; and he never talks down on you or make you feel bad. Those are the hallmarks of a good teacher. James Chan, Ph.D., Philadelphia, Pennsylvania

I agree with you

[@Innerdiamond]

Having to review mathematics after 35 years to pass the Acuplacer test for entry into new training. OMG I hated math...you make it easier and fun with understanding. No one ever explained it like you. If my teachers had, my life path would have had a different focus. Thank you and many blessings your way!

I will strong advise my colleague at the University to get the benefits of this channel
The good thing there is no advertisment 😊

[@ivanorellana322]

Whenever I watch your videos, I understand straight away. Your presentation and teachings are neat and easy to get. Thank you

[@sunshinewaychannelswc1390]

Thank you so much for all the offers you are doing
This the best educational channel I have ever seen,
Twinty years back I don't like algebra, calculus, geometry
But now with you I returned back and study just for pleasure

[@aminriff_life469]

Your videos are brilliant , well presently I'm student as a mechanical engineering and i watch all of your videos about math and physics and algebra and I'm telling you , you are the best , if i had such a teacher in my high or primary school , i would be doing so much better than what i'm already doing and also I practice English Speaking with your Videos because you speak very fluent and very great so to sume up , I'm a big fan of yours 😁

[@MathAndScience]

Thank you so very much - I really appreciate it!

[@ivylove6904]

I have been following you. You are amazing teacher. I am going to take entrance exam to become an Enroll Nurse. I struggle in Math. You help me lot in preparing for entrance exam.

[@cesarroldan6671]

A prime number is a number has two factors only, one multiplied by another number such as 2, 3, 5, 7, 11… If a number has more than two factors, they are called composite number. It’s a good idea to memorize prime numbers because they are very useful for solving fraction problems such as reducing fractions and solving algebra problems.

I do like the way you teach

[@leyanburhan7140]

thank u u helped me too much and I hope that I have a math teacher like u
God bless thank u for explaining

[@MathAndScience]

Welcome!

[@poptartz24]

Thanks, this actually helped me prepare for a math quiz.

[@winterbear1970]

thanks, this video is wonderful, and this is one of the best explanation i heard and it litterally help me

[@caribbeanman3379]

Another tip to keep in mind when creating a list of factors for a number: Once you've reached the halfway point you can stop, because a number can't have any *natural* factors greater than half its size - with the exception of the greater of its *identical* factors (1 and the number itself) and we already know as a given that the number is a factor of itself.

this is good teacher

Cool and thx for the math I'm so proud to u

[@johnnielewis9896]

great method of deduction....now is factorization used in algebra?

[@MathAndScience]

Yes definitely used in algebra.

[@avavictoriagarcia1550]

thanks bro

[@Dann287]

i have a question what if the number factor your gonna solve is the same what will happen? example factor of 16 and factor of 16 what will happen?

[@tambuwalmathsclass]

Well elaborated

Thanks so much!

Thank you

[@hemarajue2736]

I think the GCF of any two consecutive numbers is one and LCM is their product.

[@MathAndScience]

Interesting!

[@hemarajue2736]

@@MathAndScience similarly,we can find the GCF and LCM of any two consecutive even numbers easily. The GCF is always two and LCM is obtained by dividing both numbers by two and multiplying their quotients along with two.
Eg. 8,10 LCM=2.
GCF --> 8/2=4, 10/2=5,
4×5×2=40.

do you answer questions?

[@mdfurqan3223]

Can it be 3.5 times 2 is = 7?

[@Monica_L]

No, factors are only whole numbers. So, no decimals or fractions can be factors. 😀

Are GCF and HCF are same ?

to find the least common multiple I would use a 369 Tesla thing
