WebThe Fermat Primality test is a probabilistic method to determine whether the given integer is a probable prime number or not. It is based on Fermat's Little Theorem that states if p p is a prime number and a a is not divisible by p p, then a^ {p-1} \equiv 1\; (mod\;p) ap−1 ≡ 1(modp), i.e a^ {p-1} = k*p + 1 ap−1 = k ∗p + 1 (where k k is ... WebA primality test is a test to determine whether or not a given number is prime, as opposed to actually decomposing the number into its constituent prime factors (which is known as prime factorization). Primality tests come in two varieties: deterministic and probabilistic. Deterministic tests determine with absolute certainty whether a number is prime. …
