Sieve of eratosthenes prime factorization
http://duoduokou.com/algorithm/61086873942011988803.html WebTo further reduce the computational cost, the integers are first checked for any small prime divisors using either sieves similar to the sieve of Eratosthenes or trial division. Integers of special forms, such as Mersenne primes or Fermat primes, can be efficiently tested for primality if the prime factorization of p − 1 or p + 1 is known.
