WebbFermat's little theorem is a fundamental result in number theory that states that if p is a prime number and a is any integer, then ap ≡ a (mod p). This means that the remainder of the division of a^p by p is always equal to a. There are a number of applications and implications of Fermat's little theorem. The following are a few examples: Webb数論において、フェルマーの小定理（フェルマーのしょうていり、英: Fermat's little theorem ）は、素数の性質についての定理であり、実用としてもRSA暗号に応用されている定理である。

Webb24 juli 2024 · Fermat’s little theorem would become the basis for the Fermat primality test, a probabilistic method of determining whether a number is a probable prime. If we for instance want to find out whether n = 19 is prime, randomly pick 1 < a < 19, say a = 2. Calculate n − 1 = 18, and its factors: 9, 6. Webb22 maj 2024 · As a special case we have the small Fermat Theorem: ap − 1 ≡ 1 (mod p) Proof Let {a1, ⋯aφ ( n) } be a reduced residue system modulo n. Then also the set {aa1, ⋯aaφ ( n) } is a reduced residue system modulo n. Multiplying all the elements we have: a1⋯aφ ( n) ≡ (a ⋅ a1)⋯(a ⋅ aφ ( n)) ≡ aφ ( n) a1⋯aφ ( n) (mod n) WebbNow you can see that by reaching shortest path from 0 to a vertex we get the smallest possible number of "+n" parts (crucial here is that adding m doesn't change the remainder modulo m).

Some of the proofs of Fermat's little theorem given below depend on two simplifications. The first is that we may assume that a is in the range 0 ≤ a ≤ p − 1. This is a simple consequence of the laws of modular arithmetic; we are simply saying that we may first reduce a modulo p. This is consistent with reducing modulo p, as one can check.
