What is the GCF of 189 and 200 using prime factorization

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.
3 x 3 x 3 x 7 = 189
2 x 2 x 2 x 5 x 5 = 200
No common prime factors; the GCF is 1.
