What is the greatest common factor shared by 40 and 20?
The greatest common factor of 20, 21, and 25 is 1. Although 20 and 25 can be divisible by 5, 21 can not. Therefore, the only common factor between these three numbers is 1 and it's the greatest one as well.
The GCF of 25 and 40 is 5One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 25 are 1, 5, and 25.The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40.The common factors are 1 and 5. Therefore, the greatest common factor is 5.
Factors of 20: 1, 2, 4, 5, 10, 20 Factors of 25: 1, 5, 25 Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40 GCF (20, 25, 40) = 5
The only factor they have in common is 1, but they are both positive integers between 20 and 40.
The highest common factor is: 20
