What is the mystery of 6174?
6174 is a Harshad number, since it is divisible by the sum of its digits. 6174 is a 7-smooth number, i.e. none of its prime factors are greater than 7. 6174 can be written as the sum of the first three degrees of 18: 183 + 182 + 181 = 5832 + 324 + 18 = 6174.
What is the rarest number?
Therefore the number 6174 is the only number unchanged by Kaprekar’s operation our mysterious number is unique. The number 495 is the unique kernel for the operation on three digit numbers, and all three digit numbers reach 495 using the operation.
How do I find my Kaprekar number?
In mathematics, a Kaprekar number for a given base is a non-negative integer, the representation of whose square in that base can be split into two partseither or both of which may include leading zeroesthat add up to the original number. For instance, 45 is a Kaprekar number, because 452 = 2025 and 20 + 25 = 45.
