Gcf of 15 and 20

Wiki User. One way to approach this is to look at the difference between 15 and 20, which is 5. The greatest common factor of two numbers cannot be larger than the difference between the two numbers.

The GCF, or Greatest Common Factor, of two or more numbers is the largest number that evenly divides into all numbers being considered. So, the GCF of 15 and 20 would be the largest number that can divide both 15 and 20 exactly, without any remainder left afterwards. One way to find the GCF of 15 and 20 is to compare the prime factorization of each number. To find the prime factorization, you can follow the instructions for each number here:. When you compare the prime factorization of these two numbers, you can see that there are matching prime factors. You can now find the Greatest Common Factor of 15 and 20 by multiplying all the matching prime factors to get a GCF of 15 and 20 as
