Factors of 45: 1 3 5 9 15 45 Factors of 56 : 1 2 4 7 8 14 28 56 The GCF of 45 and 56 is 1 Another way to approach this is to look at the difference between 45 and 56, which is 11. The greatest common factor of two numbers cannot be larger than the difference between the two numbers. The greatest common factor of two numbers must also be a factor of the difference between the numbers. The difference, 11, is a Prime number, so the greatest common factor must be either 11 or 1. Since the numbers are not evenly divisible by 11, the greatest common factor is 1.
