## Introduction

In mathematics, the Sieve of Eratosthenes is a simple, ancient pricess for finding all prime numbers up to a specified number. It was created by Eratosthenes, an ancient Greek mathematician. However, none of his mathematical works survived-the sieve was described and attributed to Eratosthenes in the Introduction to Arithmetic by Nicomachus

## How it works

The following table deomstrates how to use the sieve of Eratosthenes to find all prime numbers by elimination, in this case up to 240.
