Harshad number

English

Etymology

Coined by Indian recreational mathematician D. R. Kaprekar, from Sanskrit हर्षद (harṣada, “giving joy”). The capitalization is likely based on mathematicians' incorrect assumption that harshad is a proper noun.

Noun

Harshad number (plural Harshad numbers)

  1. (mathematics) A positive integer which is divisible by the sum of all of its digits.
    Synonym: Niven number
    The sum of digits of 24 is 2 + 4 = 6, and 24 is divisible by 6, so 24 is a Harshad number.
