70 - Python Basics 9

Written by Emily Leng

Problem

Head over to the Python Editor and print the greatest common factor between args[0] and args[1].

Hint

Defining a function that finds a GCF will be of use.

Solution

def gcd(x, y):
    while y != 0:
        (x, y) = (y, x % y)
    return x
  
print gcd(args[0],args[1])
