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 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 n are Harshad numbers in base n.
Using this as your baseline, what is significant about this question.
This is the 400th question, and 400 is divisible by 4(4+0+0)! LOL...Good question.
ReplyDeleteIn fact after answering this question I was so pleased with it that I wrote a C program to generate Harshad Numbers...!
ReplyDelete400 is one of those numbers?
