It is not possible to give a sensible answer to this question. The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question!
The greatest common factor depends upon the other number(s) with which 60 has COMMON factors; however it will be one of the factors of 60 which are:: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30 and 60.
The Greatest Common Factor is 15.
Common factors of 44 and 60 are: 1, 2, and 4.
There is only one greatest common factor which for 60 and 72 is 12.
The greatest common factor is 6
The Greatest Common Factor (GCF) is: 5
The common factors are: 1, 2, 5, 10 The Greatest Common Factor: 10
15
55
20
60
The Greatest Common Factor (GCF) is: 1
Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 60, 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 Examples: The common factors of 18 and 60 are 1, 2, 3, and 6; the greatest common factor is 6. The common factors of 22 and 60 are 1 and 2; the greatest common factor is 2.
