Magic numbers: 1089 and 6174

[@chinthapallirangareddy1947]

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

[@chanlyelee]

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

[@IshanKishan1817]

Yes sir !

[@scottmcdonald568]

Google knows everything. Good job.

[@DashDrones]

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

[@SSA-0059]

hello sir Namaste🇮🇳, glad to see you explaining kaprekar's constant . I'm a 12th grader from D.R Kaprekar's state Maharashtra (India ) . He was a very underrated genius mathematician . Many Indians also don't know about him . happy to see you explaining his theories here . 😊

[@chanlyelee]

Thank you for your kind words, and I’m happy to be explaining his work to more people! 😊

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.

[@chanlyelee]

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!

[@PYTHAGORAS101]

@@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 KZbin. 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.

[@venikrishnan3920]

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

[@EasyElectronics2412]

I think he was from nashik

[@tscan100]

And 2 digits will revert to 9 So, can I name this the tscan100 constant? They are all the same, Kaprekar's constant. Also, in the calculations you will also see Vortex math.

[@jasonmudgarde286]

Iterative process resulting in a fixed point?

[@riadsouissi]

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

[@chanlyelee]

Thanks for the info.

[@jokarmaths7771]

amazing ...kzbin.info/www/bejne/npXKp6iFh9N4n6M

[@michellepivert3964]

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 .

[@chanlyelee]

Thanks for the sharing.

[@ergunguler3981]

Harika bir video olmuş. Teşekkür ederim.

[@ArunKumar-qv3ve]

Why the B is considered as 9 in the explanation.. please elaborate

[@fotobala33]

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

[@sr3603]

Largest four digit number using those four digits.

[@kovko69]

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

[@chinthapallirangareddy1947]

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

[@henryfayol6667]

6174 is called the Fayol’ sir Kaprekar’s constant 🤔🤔

[@chanlyelee]

Not quite! 6174 is known as **Kaprekar's constant**, named after the Indian mathematician D.R. Kaprekar. It’s famous for the "Kaprekar routine," where repeatedly arranging digits in descending and ascending order and subtracting them eventually leads to 6174.

[@aceoffools86]

Interesting...does it actually mean something? Or exist explanation why it works like that?🤔

[@aceoffools86]

(I would say im not the smartest guy and would need explanation for monkeys probably😀)

[@jogiimathew3117]

How I take this number 858 is can not take that magic number 1089

[@chanlyelee]

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

[@vishalmahanubhaw6480]

362 not work... 1089

[@chanlyelee]

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

[@mahdiabbasi420]

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

[@mahalingamr8248]

You're an LkG fail student. 362 works. It's Ramanujan's world famous renown number.

[@chinthapallirangareddy1947]

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

[@Msksosowkwjwsjosowwk]

He already told (any four digit no. where not all digits are same)...

[@akshaygawai6131]

Hello sir I am from India

[@chanlyelee]

Nice to meet you here.

[@PREGO1966]

495 will give you the same results as 6174

[@peryasami2252]

Tamil language

[@Jimmauger]

1089 Doesn’t work with 111

[@chanlyelee]

As mentioned, the last and the first digit must be different.

[@lestertorres8836]

What's the point here ...lol

[@chanlyelee]

Haha, just sharing some interesting math! 😊

[@Rajibaiju-c6j]

Bro 10-5 is 5 not 6

[@Ish-ff1ws]

495 also magical no.
