The Greatest Common Factor (GCF) of 20 and 36 is: 4
What is the greatest common factor of 20 50 and 65?

What is the relationship between common factors and greatest common factors?
Common factors are factors that are shared by a given set of numbers, usually positive integers. Greatest common factors (sometimes abbreviated to GCFs) are the factors in these given sets that have the greatest value out of all common factors. Example: Factors of 9: 1, 3, 9 Factors of 15: 1, 3, 5, 15 The common factors of 9 and 15: 1, 3 The GCF: 3
What is the greatest common factor of 15 and 20?
The GCF of 15 and 20 is 5.Since 15 = 3x5 and 20 = 2 x 2 x 5, the greatest common factor is 5.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. Since both 15 and 20 are divisible by 5, the greatest common factor is 5.Another way to determine the greatest common factor is to find all the factors of the numbers and compare them.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.The GCF is 5.Divide each number by prime numbers until it you get to 1.For example, 15 --> 5(3)20 --> 2(10) --> 2(2)(5)Compare the end results for both numbers, find the ones they have in common and multiply them together to get the gcf. In this case, it would only be 5.The GCF is 5.

What is the greatest common factor of 10 15 and 20?
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
What is the greatest common 15 and 20?
The greatest common factor of 15 and 20 is 5.
What is the greatest common factor of 20 and 45?
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
What is the greatest common factor of 14 15 and 20?
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.
What is the greatest common factor of 15 and 20 using prime factors?
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.
What are the common factors of 15and20 what is the greatest common factor gcf of 16and 20?
15 and 20: 10, 5, 1 16 and 20: 4
Three pairs of factors that there greatest common factor is 5?
5 and 10 10 and 15 15 and 20
What is the greatest common factor of 20 and 90?
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
What are the greatest common factors of 17 and 20?
The factors of 17 are: 1, 17 The factors of 20 are: 1, 2, 4, 5, 10, 20 The common factors are: 1 The Greatest Common Factor: 1
What are the common factors and greatest common factor of 10 and 20?
1,2,5,10 are the common factors, and the Greatest Common Factor is 10.
What is the greatest factor of 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.
