What is the greatest common factor of 33 and 40?

Answer 1

You need at least two numbers to find a GCF.

Answer 2

1 because the the prime factorization of 10=2*5 and 33=3*11. Because they have nothing in common, the answer is one.

Answer 3

The GCF of 10 and 32 is 2.

The factors of 32 are 1,2,4, 8, 16, and 32

The factors of 10 are 1,2 5, and 10

So the answer is 2

Answer 4

"Common" means "same for both". There's nothing 'common' about one single thing,

and there are no 'common' factors until you have at least two numbers.

Answer 5

The GCF is 1.

Answer 6

2 is.
