WebMay 28, 2024 · The Sieve of Eratosthenes is an algorithm used to find all prime numbers less than a number. The way it works is that, starting from 2, it creates a list of all integers from there until n. Then, starting with 2 (which is the smallest prime), every multiple of 2 is marked as not a prime. Next, find the next number that's greater than 2 that ... WebA prime number is a natural number that has exactly two distinct natural number divisors: the number 1 and itself.
