TC1014: Python Loops Number6

Program#6
Ask the user for two integers a and b. Calculate the gcd (Greatest Common Divisor) of a and b using a loop and the following properties of gcd(a,b):
gcd(a,a) = a
If a is bigger than b then gcd(a,b) is gcd(a-b,b)
So an example run would look like the following if the user requested 28 and 152.
Enter the smaller value: 28
Enter a value greater than or equal to 28: 152
The GCD of 28 and 152 is 4.
