What is a neon number?

Why is 1 a Kaprekar number?

The universal Kaprekar number 1 corresponds to the unitary divisor 1 of 10n – 1, which is why we allow unity as a Kaprekar number. For each n >= 1 , we disallow 10n as a Kaprekar number since it is the vacuous solution to (1) and (2) when N = 10n .

Kaprekar also described the harshad numbers which he named harshad, meaning “giving joy” (Sanskrit harsha, joy +da taddhita pratyaya, causative); these are defined by the property that they are divisible by the sum of their digits. Thus 12, which is divisible by 1 + 2 = 3, is a harshad number.

In mathematics, a harshad number (or Niven number) in a given number base is an integer that is divisible by the sum of its digits when written in that base. Harshad numbers in base n are also known as n-harshad (or n-Niven) numbers. Harshad numbers were defined by D. R. Kaprekar, a mathematician from India.
