There isn't one. You need to know the multiplication tables, and think how they apply to each number.
example: 24 and 36
both belong to the 3's mult. table so 3 is a common factor (3x8 and 3x12)
but they also belong to the 4's Mult table so 4 is a common factor (4x6 and 4x9)
but they also belong to the 12's Mult table so 12 is a common factor (2x12 and 3x12)
3, 4, and 12 are common factors, but the GCF is 12
