A clever mathematical trick (due to Euclid) makes it easy to find greatest common divisors. Suppose that a and b are two positive integers: ・If b = 0, then the answer is a ・Otherwise, gcd(a, b) is the same as gcd(b, a % b) See this website for an example of Euclid's algorithm being used to find the gcd. http://en.wikipedia.org/wiki/Euclidean_alg…
def gcdIter(a, b):
'''
a, b: positive integers
returns: a positive integer, the greatest common divisor of a & b.
'''
testValue = min(a, b)
# Keep looping until testValue divides both a & b evenly
while a % testValue != 0 or b % testValue != 0:
