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. It does so by iteratively marking as composite (i.e., not prime) the multiples of each prime, starting with the first prime number, 2. The multiples of a given prime are generated as a sequence of numbers starting from that prime, with constant difference between them that is equal to that pri…
