table of factors of small Mersenne numbers
The following table lists the prime factors![]()
for some small Mersenne numbers, specifically, numbers of the form where is a prime in the range and is composite. Thus, the following values of have been left off the table: 2, 3, 5, 7, 13, 17, 19, 31, 61, 89, 107, 127 and all primes greater than 199 (see table of Mersenne primes). The numbers get quite large, and correspondingly, so do their factors. All these numbers are squarefree
