How fast is a good time to factor the highest number for a long: 9,223,372,036,854,775,807? Using my algorithm on my laptop with a core i5 @ 2.79 gHz, I got the factors (not just primes) and sorted them from least to greatest in 25.270 seconds; 25.611 seconds without sorting... It's usually faster when it has to order the number, why is that?

Is this a good time or could it be faster?
