WebSieve of Eratosthenes is an algorithm that helps to find all the prime numbers less than a number N. The algorithm works by removing the numbers not meeting some mentioned criteria. Hence, the multiples of known prime numbers get eliminated, and the time to find all the prime numbers up to a limit is minimum. WebSieve of Eratosthenes . The most efficient way to find all of the small primes (say all those less than 10,000,000) is by using a sieve such as the Sieve of Eratosthenes(ca 240 BC): . … WebSieve of Eratosthenes is an algorithm in which we find out the prime numbers less than N. Here N is an integer value. This is an efficient method to find out the prime numbers to a limit. By using this we can find out the prime numbers till 10000000. Here the basic approach is used we just make a memory of size N-1. dwarf fortress best world settings
