WebbHe stated four primality-related theorems. The most famous of these, Proth"s theorem, can be used to test whether a Proth number (a number of the form k2n + 1 with k odd and k < 2n) is prime. The numbers passing this test are called Proth primes. They continue to be of importance in the computational search for large prime numbers. WebbIn number theory, Proth's theorem is a primality test for Proth numbers . It states [1] [2] that if p is a Proth number, of the form k 2 n + 1 with k odd and k < 2 n, and if there exists an …

Webb5 aug. 2024 · 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 a ( p 1 ) 2 1 mod p , then p is prime. In this case p is called a Proth prime. This is a pract WebbProth's Theorem. Let N = k. 2 n +1 with k odd and 2 n > k . Choose an integer a so that the Jacobi symbol ( a, N) is -1. Then N is prime if and only if a(N-1)/2 ≡ -1 ( mod N ). This … WebbA Generalization of Proth’s Theorem In this section we shall state and prove theorems 2.3 and 2.5, whose provide a simple primality test for generalized Proth’s numbers N = Kpn+1. To prove the theorems we require two lemmas. Lemma 2.1. Assume that A,P are integers with 1 ≤ A ≤ P. If there is an integer D > 0 such that gables downtown dallas
