Program to find prime factor in python
WebYour first test number, a1 = 771895004973090566, can be factored in less than 1/2000 second (or better), because it is 2 x 385947502486545283. The factor 2 is of course found instantly. Then, 385947502486545283 is easily determined to be prime using Miller–Rabin.
