Roughly speaking, th...

In number theory, Proth's theorem is a primality test for Proth numbers. It states that if p is a Proth number, of the form k2n + 1 with k odd and k < 2n, and if there exists an integer a for which then p is prime. In this case p is called a Proth prime. This is a practical test because if p is prime, any chosen a ha...
