Generating large prime numbers

WebApr 18, 2024 · One can generate prime numbers using Fermat's little theorem. This theorem states that if p is prime and a ≠ 0 mod p then: a p − 1 = 1 mod p Suppose then that for some number n and some a ≠ 0 mod n the above equation would hold when taking p equal to n. Then that doesn't prove that n is prime. WebJun 27, 2024 · Initially, let p be equal 2, the first prime number.
