WebSep 12, 2024 · 2. Firstly, it's not any integer. It's only integers not divisible by p. Secondly, you might want to understand the variant of Fermat's little theorem which says that a p ≡ a ( mod p) (which does work for all a. This one can be seen easily from the formula ( a + b) p ≡ a p + b p ( mod p), which follows from binomial expansion, and induction. WebCorollary 9.2 (Fermat’s little Theorem). Let p be a prime and let a be an integer. If a is coprime to p then ap 1 1 mod p: In particular ap a mod p: Proof. ’(p) = p 1 and so the rst statement follows from (9.1). For the second statement there are two cases. If (a;p) = 1 multiply both sides of ap 1 1 mod p by a.

WebDec 4, 2024 · Take an Example How Fermat’s little theorem works. Example 1: P = an integer Prime number a = an integer which is not multiple of P Let a = 2 and P = 17 … WebJul 7, 2024 · If n and p are distinct primes, we know that p n − 1 = n 1. The Fermat primality test for n consists of testing for example whether 2 n − 1 = n 1. However, the converse of Fermat’s little theorem is not true! So even if 2 n − 1 = n 1, it could be that n is not prime; we will discuss this possibility at the end of this section. البرتو دلریو کشتی کج
