## Array formula to check if a number is prime [just for fun]

Published on May 29, 2009 in Learn Excel

During my 3rd year of graduation I went and purchased the volume 2 of Donald Knuth’s Art of Computer Programming and thus began my love with all things random and prime. I never really became the math-geek I always wanted to, instead I became an insurance expert with tons of passion for data and visualization. But when I get a chance to poke with randomness or numbers, I always lap it up with joy. And that brings us to an interesting array formula trick to check if a number is prime or not.

hit ctrl+shift+enter and bingo, it tells you if the number is prime or not. Read on to find how it works
