WebUsing the Fermat test, we got a benchmark of 45006 function calls in 0.885 seconds., but you run a higher chance of pseudoprimes. So, if just needing to check if a number is prime or not, the first method for is_prime works just fine. … WebDec 29, 2016 · Although the Fermat primality test is the quickest, you do have the chance of false results on pseudoprimes. It is better to go with either the Miller-Rabin or the Solovay-Strassen algorithms. For speed and efficiency, the Miller- Rabin preforms roughly four times faster than the Solovay-Strassen. #python #math #algorithm #benchmark #prime
