Sieve of Eratosthenes

This is a visualization of the Sieve of Eratosthenes used to find the primes up to 100. We only need to check for divisibility by primes up to 7, which is the largest prime less than the square root of 100 so we find these primes relatively quickly.

Thanks!

There are many other videos describing this Sieve - my hope for this video is that by watching it, you get a feel for the sieve and can figure out what is going on.
