WebSieve of Eratosthenes This algorithm finds all primes numbers from 2 to n. We assume that all the numbers in this range are prime at the start, i.e. mark them as potential candidates for prime numbers. In the following steps, we look at the first marked number, considering this to be a prime number. WebAlgorithm Sieve of Eratosthenes is a simple and ancient algorithm (over 2200 years old) used to find the prime numbers up to any given limit. It is one of the most efficient ways to find small prime numbers (<= $10^8$ ). For a given upper limit the algorithm works by iteratively marking the multiples of primes as composite, starting from 2. maurices headquarters address
