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. Since 15 over 45 is a single rational number, you have only one number in the question! .
Since 15 is a factor of 45, it is automatically the GCF.
The GCF for 15 30 45 is 15.The GCF is 15.It is: 15
The GCF is 15.
The greatest common factor (GCF) of 15, 45, and 540 is 15.
