Interesting, I actually had to augment the source code in MATLAB in order to do Problem 3.

For some reason MATLAB arbitrarily sets a limit on prime factoring numbers larger than 2^32. Opened up the factor.m and changed it to 2^50, so this solution pretty much became a one-liner.

Problem 3 Code: %% Euler Project - Problem 3 % The prime factors of 13195 are 5, 7, 13 and 29. % What is the largest prime factor of the number 600851475143? pf = factor(600851475143); lpf = max(pf)
