title: General number field sieve; factorizing 200 digit number
body: <p>I'm fairly new in programming, and not really looking into the specifications of how things work. All I need is an efficient way of factorizing a 200 digit number. I've heard that General number field sieve is the best algorithm for that. Is there any code in python written that would implement this idea? Or are there any other alternatives? Any help would be appreciated</p>
