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 GCF is 95.
The GCF is 5.
The GCF is 19.
The GCF is 5.
The GCF is 5.
The GCF is 5.
The GCF is 19.
GCF(95, 54) = 1
The GCF is 5.
GCF(95, 38, 57) = 19.
Gcf(133, 152, 95) = 19 gcf(13, 31, 52, 95) = 1
Since 19 is a factor of 95, it is automatically the GCF.
