WebSieve of Eratosthenes (1) A classical method of extracting prime numbers is by the sieve of Eratosthenes more than two thousand years ago (Bokhari, 1987). The 1st number of prime is 2 and it is kept. All multiples of this number are deleted as they cannot be prime. Repeat with each remaining number. The algorithm removes non primes, leaving ... In mathematics, the sieve of Eratosthenes is an ancient algorithm for finding all prime numbers up to any given limit. It does so by iteratively marking as composite (i.e., not prime) the multiples of each prime, starting with the first prime number, 2. The multiples of a given prime are generated as a sequence of numbers starting from that prime, with constant difference between them that is equal to that pri…
