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 factor of any number is itself. Prime factorisation is irrelevant in finding the GCF of a single number.
1+1=1 is the GCF of 189 and 200
Factors of 189: 1,3,7,9,21,27,63,189 Factors of 200: 1,2,4,5,8,10,20,25,40,50,100,200 Their only common factor is 1.
