Sieve of Eratosthenes - Wikipedia
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… WebEratosthenes: 1 n Greek mathematician and astronomer who estimated the circumference of the earth and the distances to the Moon and sun (276-194 BC) Example of: … mary capule ashland va

WebMay 23, 2024 · If you will be searching through primes repeatedly, creating and reusing a table of all primes below a reasonable limit (say 1,000,000) will be faster. Here is another example using gmpy2 and the Sieve of Eratosthenes to create a table of primes. primes2() returns primes from the table first and then uses next_prime(). WebIn addition to calculating the earth’s circumference and the distances from the earth to the moon and sun, the Greek polymath Eratosthenes (c. 276-c. 194 BCE) devised a method for finding prime numbers.
