Friday Puzzler: Sieve of Eratosthenes

This post is more than 2 years old.

It's been a long time since I posted a Friday Puzzler, but as I was perusing Khan's CS courses this morning (which look really cool!) I came across this fascinating discourse on prime numbers: Sieve of Eratosthenes.

Your challenge today is simple - watch the video (via the link above or embed below) - and once the theory is discussed, do not look at the full solution. Write up a solution in ColdFusion and post your answer below. Please remember to use a Gist or Pastebin link.

As a prize today I can offer four gold badges, two Klout perks, and a couple Facebook likes.
