    6174 is called kaprekar constant, invented by Indian mathematician D.R kaprekar

      Absolutely! 6174 is indeed the fascinating Kaprekar constant. Such an interesting discovery by D.R. Kaprekar-thank you for sharing this with everyone! 🙌

    This is from Mr Kaprekar from Mumbai, India who was a teacher. He was a genius.

    Hi, very fascinating numbers.
    Let me know if you like my magic fractions. A= 244000, B= 31241, C=4000
    Both A/B and B/C are equal to the square root of 61 @ approximately 8 digits of precision and when you add A/B and B/C together and divide the result by 2 the precision magically :) doubles to approximately 16 digits of the square root of 61.
    I can do fractions like this for any number and any minimal precision, I was going to do 6174 but I wanted to use smaller numbers for this comment.

      Wow, that’s really fascinating! It’s amazing how the precision doubles when you average them like that. I’d love to learn more about how you create these magic fractions for any number. Thanks for sharing such an intriguing example!

      @@chanlyelee I battled for years trying to figure out how to do these fractions and I feel a bit reluctant to just hand out the sequence formula in the comments section on UA-cam. I am just teasing people at the moment to see if there is any interest for this kind of stuff. I am considering putting it on the market because I am unemployed and getting old. Can I ask, if I put it on the market would you pay say $11 Australian for this?
      I see you have 369 likes for your video, nice. a = 2559015, b = 133217, c = 6935
      a/b and b/c give 9 digits of precision for the square root of 369
      (a/b + b/c)/2 results in 18 digits precision.

    Both 1089 and 6174 in any order will be divisible by 9. Eg 9081(1009) and 7164(796)

    6174 is a Kaprekar constant in base 10.
    Next one is 631764.

    comment démolir 6174 ? je vous donne 67914 ! et si vous n'avez pas envie de faire les calculs je donne la solution sur la vidéo de Pascal Bourdeau .

    Not every four digit number four digit number having same value does not stand for the test! Ex: 1111,2222,3333 etc

    While explaining about 6174 , how number 8352 has changed to 8532 in the middle? Please explain. 8352-2358 = 5994 and not 6174.

      Largest four digit number using those four digits.

    • @kovko69
      @kovko69 12 днів тому

      It's not only the largest four digit number, but it would also inevitably end up being 6174 anyway lol.

    • @chinthapallirangareddy1947
      @chinthapallirangareddy1947 7 днів тому

      That is the biggest number which can be made with four digits of the given number sir

    362 not work... 1089

    • @chanlyelee
      @chanlyelee  20 днів тому

      As mentioned, if you get 99 in the middle step, write it as 099 and process. Please try it again. 😆

      It works:
      632-236=396
      396+693=1089

      As mentioned in the video,for the three digit abc, a must be not equal to c.
