WebMar 12, 2024 · The Sieve of Eratosthenes is an algorithm for finding prime numbers up to a given natural number by gradually screening out composite numbers. Figuratively speaking, composite numbers slip through the sieve of Eratosthenes in the process of shaking it, and the simple ones remain in the sieve. To understand this algorithm, remember that … WebMar 7, 2024 · The Sieve of Pritchard is an algorithm for finding the prime numbers up to a given limit N, published in 1981. It considers many fewer composite numbers than the Sieve of Eratosthenes (and has a better asymptotic time complexity). However, unlike the latter, it cannot be modified to greatly reduce its space requirement, making it unsuitable for very …
