A single number does not have a common factor. Common factors are factors that two or more numbers have in common. The greatest common factor of a pair of numbers over 50 could be any number, depending on the pair of numbers. The greatest common factor of 51 and 100 is 1. The greatest common factor of 51, 52, 53, 54, 55, and 56 is 1. The greatest common factor of 52 and 100 is 2. The greatest common factor of 57 and 102 is 3.
the greatest common factor is 6
The greatest common factor is 5 because it is the biggest number that will go into both with nothing left over.
none the number is a factor

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! That number is 15/45, a fraction that is smaller than 1. The concept of factors makes sense in context of whole numbers since otherwise every non-zero number is a factor of every number.
