The Sieve of Eratosthenes Is Your Friend for Finding Prime Numbers

The Sieve of Eratosthenes is an ancient math algorithm created by Eratosthenes of Cyrene, explains Divine Orji, which is used to find all prime numbers between 0 and a given limit.

Basically, Orji says, “the algorithm loops through all numbers between 0 and our input. In each iteration, if the number is a prime, it marks all multiples of that number as non-primes.”

In this article, Orji demonstrates how to use the Sieve of Eratosthenes to solve a simple coding challenge.
