2 x 6 = 12
2 x 9 = 18
2 x 13 = 26

Answer 4

The common factors are 1 and 2 and so the GCF is 2.

Answer 5

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.

Answer 6

A common factor (HCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question! Consequently, the question makes no sense.
