6174 is known as Kaprekar's constant after the Indian mathematician D. R. Kaprekar. This number is notable for the following properties :

  • Take any four-digit number, using at least two different digits. (Leading zeros are allowed.)
  • Arrange the digits in descending and then in ascending order to get two four-digit numbers, adding leading zeros if necessary.
  • Subtract the smaller number from the bigger number.
  • Go back to step 2 and repeat.

You will get the 6174....
