Primality check

WebPrime number is a number, which have exactly two distinct natural number divisors, 1 and itself. The most naive approach to check whether a number is prime is to follow the definition. Algorithm to check number's n primality: otherwise, for all integers m from 2 to n - 1, check if n is divisible by m. If it is, n is composite; WebA Primality Test.
