Fermat’s little theorem gives a condition that a prime must satisfy: Theorem. If P is a prime, then for any integer A, (A P – A) must be divisible by P. 2 9 – 2 = 510, is not divisible by 9, so it cannot be prime. 3 5 – 3 = 240, is divisible by 5, because 5 is prime. This may be a good time to explain the ...
Fermat's little theorem states that if p is a prime number, then for any integer a, the number is an integer multiple of p. In the notation of modular arithmetic, this is expressed as For example, if a = 2 and p = 7, then 2 = 128, and 128 − 2 = 126 = 7 × 18 is an integer multiple of 7. If a is not divisible by p, that is if a is coprime to p, Fermat's little theorem is equivalent to the stat…
