What is the greatest common factor of 22 and 40?
The factors of 22 are 1, 2, 11, and 22.The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40.The largest factor they have in common is 2, therefore 2 is the greatest common factor.Or, you can use the prime factors to determine the greatest common factor.The prime factors of 22 are 2 and 11.The prime factors of 40 are 2, 2, 2, and 5.The prime factors they have in common are a single 2, so 2 is the greatest common factor.The GCF is 2.
What is the greatest common factor of 10 and 45?
The GCF of 10 and 45 is 5 The factors of 10 are 1, 2, 5, and 10. The factors of 45 are 1, 3, 5, 9, 15, and 45. The largest factor they have in common is 5, so 5 is the greatest common factor. Or, you can use prime factors. The prime factors of 10 are 2 and 5. The prime factors of 45 are 3, 3, and 5. The prime factors they have in common are a single 5, so 5 is the greatest common factor.
What common factors of 48 equal negative 13?
You could use -12 and -1 or -16 and 3.
Greatest common factor of 28?
One number can not have a common factor so there is NO GCF.. you need at least 2 You would use common factors for fractions, so to find the GCF you need 2 factors. (Assuming 1 and 28 here, it would be 28)

How do you know whether to use the greatest common factor or the least common multiple to solve a problem?
the least common multiple is what the numbers you are using divide into. e.g. 3 and 6 have 12 as the common factor. the greatest common factor is what divides into your numbers. 6 and 9 have 3 as the greatest common factor
