Prime Decomposition
|
|
Description
|
Using a combination of divisibility tests and methods inspired by fermat factorization, this program can find the prime decomposition of a number with remarkable speed and efficiency. Fermat factorization is usefull for factoring large numbers that are known to be the product of two primes relativly close to the square root. For example, this program factors 12240467203 into 100003*122401 in around 10sec. This updated version is more memory efficient than the original.

Note! This review was written for a previous version of this file!
This program is amazing. It factored an eight-digit number in about twenty seconds. (9419 * 1933 = 18206927) This is truly impressive work from Mr. Blair.
