Python – Find Factors of Number

wearetherock — Sun, 30 Aug 2009 17:44:04 +0000

Code :
========================================

from math import sqrt
import sys

input = int(sys.argv[1])
factors = []
min_fac = 2

while input > min_fac - 1 :
        if (input % min_fac) == 0 :
                factors.append(min_fac)
                input = input / min_fac
        else :
                min_fac += 1
print factors
