1 and 5, the GCF.
The greatest common factor of 10, 15, and 20 is 5.A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common.One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 10 are 1, 2, 5, and 10.The factors of 15 are 1, 3, 5, and 15.The factors of 20 are 1, 2, 4, 5, 10, and 20.The common factors are 1 and 5. Therefore, the greatest common factor is 5.If you mean: 10, 15 and 20 then it is 5 that is the greatest common factor
The greatest common factor of 15 and 20 is 5.
A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 14 are 1, 2, 7, and 14. The factors of 15 are 1, 3, 5, and 15. The factors of 20 are 1, 2, 4, 5, 10, and 20. The only common factor is 1. Therefore, the greatest common factor is 1.
The greatest common factor of 20 and 45 is 5.The factors of 20 are: 1, 2, 4, 5, 10, 20The factors of 45 are: 1, 3, 5, 9, 15, 45The common factors are: 1, 5
Prime factors of 15 are 3 x 5Prime factors of 20 are 2 x 2 x 55 is the greatest common factor of 15 and 20.
15 and 20: 10, 5, 1 16 and 20: 4
5 and 10 10 and 15 15 and 20
The greatest factor of 15 is 15. The greatest factor of 20 is 20. The greatest common factor of 15 and 20 is 5.
The Greatest Common Factor of 20 and 90 is 10, because the factors of 20 are: 20:1,2,4,5,10,20 The factors of 90 are: 90:1,2,3,5,6,9,10,15,18,30,45,90 So, the common factors are 1,2,5,10 10 is the greatest number of them so 10 is the Greatest Common Factor. THE ANSWER IS 10
The greatest common factor of 15, 20, and 25 is 5.
1,2,5,10 are the common factors, and the Greatest Common Factor is 10.
