Lehmer - Mar 7, 2021 · Lehmer's GCD algorithm, named after Derrick Henry Lehmer, is a fast GCD algorithm, an improvement on the simpler but slower Euclidean algorithm.It is mainly used for big integers that have a representation as a string of digits relative to some chosen numeral system base, say β = 1000 or β = 2 32.

 
The Lucas-Lehmer test is an efficient deterministic primality test for determining if a Mersenne number M_n is prime. Since it is known that Mersenne numbers can only be prime for prime subscripts, attention can be restricted to Mersenne numbers of the form M_p=2^p-1, where p is an odd prime. Consider the recurrence equation s_n=s_(n-1)^2-2 (mod M_p) (1) with s_0=4. For example, ignoring the .... Raising canepercent27s loyola
