http://nlvm.usu.edu/en/applets/doc/sieve/help.html WebSieve of Eratosthenes is a simple and ancient algorithm (over 2200 years old) used to find the prime numbers up to any given limit. It is one of the most efficient ways to find small prime numbers (<= $10^8$ ). For a given upper limit the algorithm works by iteratively marking the multiples of primes as composite, starting from 2.
