A Harshad number, or Niven number, is an integer that is divisible by the sum of its digits in a given number base. Harshad numbers were defined by D. R. Kaprekar, a mathematician from India. The word "Harshad" comes from the Sanskrit harṣa, meaning "great joy". The Niven numbers take their name from Ivan M. Niven from a paper delivered at a conference on number theory in 1997. All integers between zero and the base number are Harshad numbers.
