A primality test is an algorithm for determining whether an input number is prime. Among other fields of mathematics, it is used for cryptography. Unlike integer factorization, primality tests do not generally give prime factors, only stating whether the input number is prime or not. Factorization is thought to be a computationally difficult problem, whereas primality testing is comparatively easy (its running time is polynomial in the size of the input). Some primality tests pr… WebA prime number is defined as a natural number greater than 1 and is divisible by only 1 and itself. In other words, the prime number is a positive integer greater than 1 that has exactly two factors, 1 and the number itself. First few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, …
