WebFeb 23, 2024 · The sieve of Eratosthenes operates in a relatively straightforward manner. The first stage entails generating a table with all the positive numbers whose primality is to be checked, starting with 2, listed in ascending order. The number 1 does not need to be in the table because it is not a prime number. In mathematics, the sieve of Eratosthenes is an ancient algorithm for finding all prime numbers up to any given limit.
