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.

What are the common factors and the greatest common factors for 15 and 40?
The common factors are: 1, 5 The Greatest Common Factor (GCF) is: 5
What are the common factors and greatest common factor of 5?
There is neither a greatest common factor nor common factors of a single number, such as 5, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 5 are 1 and 5. The prime factor of 5 is 5. Examples: The common factors of 5 and 7 are only 1; the greatest common factor is 1. The common factors of 5 and 110 are 1 and 5; the greatest common factor is 5.
What are the greatest common factors for 40 125?
The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40 The factors of 125 are: 1, 5, 25, 125 The common factors are: 1, 5 The Greatest Common Factor: 5
What is the greatest common factor of 85 and 145?
One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 85 are 1, 5, 17, and 85. The factors of 145 are 1, 5, 29, and 145. The common factors are 1 and 5. Therefore, the greatest common factor is 5. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 85 are 5 and 17. The prime factors of 145 are 5 and 29. The prime factors in common are a single 5, so the greatest common factor is 5.
What is the greatest common factor of 20 and 55?
One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 20 are 1, 2, 4, 5, 10, and 20. The factors of 55 are 1, 5, 11, and 55. The common factors are 1 and 5. Therefore, the greatest common factor is 5. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 20 are 2, 2, and 5. The prime factors of 55 are 5 and 11. The prime factors in common are a single 5, so the greatest common factor is 5.

The greatest common factor is 5
What is the greatest common factor of 10 and 75?
One way to determine the 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 75 are 1, 3, 5, 15, 25, and 75. The common factors are 1 and 5. Therefore, the greatest common factor is 5. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 10 are 2 and 5. The prime factors of 75 are 3, 5, and 5. The prime factors in common are a single 5, so the greatest common factor is 5. Answer: 5
What is the greatest common factor of 15 and 65s?
The GCF of 15 and 65 is 5. One 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 65 are 1, 5, 13, and 65. The common factors are 1 and 5. Therefore, the greatest common factor is 5. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 15 are 3 and 5. The prime factors of 65 are 5 and 13. The common prime factors are a single 5, so the greatest common factor is 5.
