The greatest factors of any positive integers are the integers themselves. The GCF of 28 and 60 is 4.
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.
