Web5 de jun. de 2024 · Therefore the highest prime number to be found with Sieve of Erastosthenes is 32*10^9-1 with 4GB RAM. With Segmented Sieve Of Eratosthenes we can square this number, which then results in 10^21-1. Another way to go further is to use the hard disk instead of RAM to store the bits for Sieve of Erastosthenes. Web26 de mai. de 2015 · $\begingroup$ Code needs a small correctness edit, but even that naive trial division is much faster than sieving all numbers up to N every time. Set N to 10,000,000,000. Run prevprime 1000 times. Even a very fast sieve will take 2+ seconds per call. Doing the trivial trial division is 1000x faster. smart city template free download
