WebMar 25, 2024 · We can conclude that one of the numbers is <= sqrt (n), and the other one is >= sqrt (n). And to prove that n is prime, we just need to find one of the numbers - a or b. If no such number exists, it means that n is not prime. Hence, to do the primality test, we need not run loop till n, this can be done by running the loop till sqrt (n) itself.
