The Sieve of Eratosthenes

The Sieve of Eratosthenes is a method for finding all prime numbers up to a certain limit. It starts by listing all numbers from 2 to your chosen number. Then, it systematically removes multiples of each prime number, beginning with 2, because multiples of 2 (like 4, 6, 8) are not prime. After removing multiples of 2, move to the next remaining number and remove its multiples, continuing this process. The remaining numbers that are not eliminated are prime. This efficient method visually shows how primes are spaced and helps identify them quickly.
