Kaprekar constant
The number 6174 is called the Kaprekar constant. It was discovered by the Indian Mathematician Kaprekar.
We get this constant if we perform certain routine calculations to any four-digit number.
The rule is
1. Take any 4 digit number.
2. Arrange the digits of the 4 digit number in descending and ascending order.
3. Subtract the smaller number from the bigger number
4. Repeat the steps from 2 for the answer obtained also.
Repeat the steps till you reach 6174.
We always end up with 6174. Once you reach 6174, the process will continue generating the same number.
Let us solve an example to understand this..
