The factors of 20 are: 1, 2, 4, 5, 10, 20
The factors of 25 are: 1, 5, 25
The GCF is 5.
The factors of 75 are: 1, 3, 5, 15, 25, 75 The factors of 100 are: 1, 2, 4, 5, 10, 20, 25, 50, 100 The common factors are: 1, 5, 25 The Greatest Common Factor: GCF = 25
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 25: 1, 5, 25 Factors of 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 Factors of 75: 1, 3, 5, 15, 25, 75
Find all the factors of each of the numbers. 25 - 1, 5, 25 35- 1, 5, 7, 35 The common factors are 1 and 5. The largest of these (5) is the GCF.
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
5The factors of 20 are: 1, 2, 4, 5, 10, 20The factors of 25 are: 1, 5, 25The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40The Greatest Common Factor (GCF) is: 5The GCF is 5.The GCF is 5.
The GCF is 5.
The GCF is 5.
The GCF of 15 and 27 is 3. The GCF of 15, 20 and 25 is 5. The GCF of 15, 27, 15, 20 and 25 is 1.
The factors of 75 are:1, 3, 5, 15, 25, 75The factors of 500 are:1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500The common factors are:1, 5, 25The Greatest Common Factor (GCF) is:25
There cannot be a greatest common factor (GCF) of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.
