To find the prime factors of any number up to 2^32 (about 4.3*10^9), you can use MATLAB's built-in function factor.m

For integers greater than 2^32, try this program, which guarantees a result up to 10^14, thus extending the domain of inputs 23,000-fold.

(This file is an adaptation of MATLAB's function primes.m)

Example:

myfactor(2^32+1)
ans = [1 641 6700417]
