How do you find every prime up to n without testing any number for divisibility? Take the first unmarked number p, mark all its multiples from p² onward, then move to the next unmarked number. A composite m has a prime factor of at most √m, so only primes p ≤ √n are needed. For n = 100 that means 2, 3, 5 and 7, and the 25 survivors are the primes below 100. Every composite is struck out by its smallest prime factor, and the total work is about n log log n steps, nearly linear in n.
