You may use it to test any suitable number as you … WebIn general, primality tests can only tell you that a number n either ‘is composite’, or ‘can’t tell’. They cannot confirm that n is prime. However, under the special circumstance that we can factor n−1, primality can be proved: Theorem 4.1 ( Lucas Test, as strengthened by Kraitchik and Lehmer). Let n > 1 have

WebJan 17, 2009 · This is a test that for an integer N can probabilistically classify it as prime or not, and repeated tests can increase the correctness probability. The slow part of the test itself mostly involves computing a value similar to A^ (N-1) modulo N. Anyone implementing RSA public-key encryption variants has used this algorithm. Web2. Probabilistic primality tests A probabilistic primality test has the following general framework: For each odd positive n a set W(n) ⊆ Z n = {0, 1,..., n−1} is defined having the following properties: 1. given a ∈ Z n, it can be checked in deterministic polynomial time whether a ∈ W(n); 2. if n is prime then W(n) = ∅;
