Sieve of Eratosthenes - Mathematics Stack Exchange
WebSieve 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. WebWith an Eratosthenes’ sieve, the multiples of each prime number are progressively crossed out of the list of all numbers being examined (in this case the numbers one to two hundred, 1 to 200). You will notice that by the time you come to crossing out the multiples of three , several have already been crossed out: 6, 12, 18 etc. WebMar 24, 2024 · Sieve of Eratosthenes. An algorithm for making tables of primes. Sequentially write down the integers from 2 to the highest number you wish to include in the table.
