The GCF is 6.
7
The GCF is... 12
The GCF is 6.
The greatest common factor of 6, 12, and 42 is 6.6 x 1 = 66 x 2 = 126 x 7 = 42
The GCF of the numbers 6, 12, and 30 is the number 6.
The GCF/HCF of 12 and 90 is 6.
I'm not sure exactly what you mean by "pair of no.12" There is no factor pair of 12 that has a GCF of 6. There is a pair of factors of 12 (6 and 12) that have a GCF of 6. There is a pair of numbers that add up to 12 (6 and 6) that have a GCF of 6. 6 and any multiple of 6 have a GCF of 6. Any multiples of 6 that differ by 6 have a GCF of 6.
The GCF is 6.
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!
What is the GCF of 6 and 12 and 45?The GCF of 6, 12, and 45 is, 3.
The GCF is 3.
