Harshad Number

I never knew that a particular type of numbers have been named after me.

A Harshad number, or Niven number, is an integer that is divisible by the sum of its digits in a given number base. The Niven numbers take their name from Ivan M. Niven from a paper delivered at a conference on number theory in 1997. All numbers between zero and the base number are Harshad numbers. Not that I understood much of this explanation, but it’s cool anyway 🙂 I haven’t as yet found the reason why these numbers as known as Harshad Numbers. Although my dad is very much a maths and stats person, as these numbers were discovered only in 1997, I can be sure that I wasn’t named after them. So I will presume that it’s the other way around 🙂
