Web1. This animation also nicely illustrates the fact that, to find all the primes up to some maximum n, you only need to sieve out multiples of primes less than n. (Here, n = 120 < 11 2 = 121, so the only primes whose multiples need to be sieved out are 2, 3, 5 and 7.) After that, all the remaining unsieved numbers will be primes.

WebApr 10, 2024 · In the end when all primes are finnished we will merge the list of primes. we start by sequentially finding the primes up to sqrt (n) we now have a list of all the primes needed to sieve the rest of the numbers. I will now divide evenly the primes found to all the thrrads. Each thread will now sieve from the primes they have to n, in the end ...
