Project 92: Variables 'a' and 'b' have been initialized. You can assume these are both positive integers.
Task: Appropriately initialize the value of 'gcf' that represents the greatest common factor between a and b.
Example: if a = 10 and b = 15, then gcf = 5
Example: If a = 30 and b = 20, then gcf = 10
