"GCF"s are usually only relevant to numbers, not to algebraic expressions. But even if they applied to expressions, the "C" in GCF stands for "common", which means "same for both", and you only listed a single excpression, so there can't be anything 'common' about it. In short, your question loses in at least two ways.
You need at least two expressions to find something in common between them. The GCF of 2x and 10 is 2.
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 (or expressions). Although it may not appear so, xyz + xy is only one expression.
The GCF of 4, 8 and 9 is 1.
The GCF is 16.
The GCF is 9w.
9w
The GCF is 4r.

You need at least two terms to find a GCF.
The GCF is 12.
The GCF is 3n.
The GCF is 13xy.
The GCF is 13xy.
I don't know what expressions you have to choose from, but the GCF of those numbers is 22.
You need at least two expressions to find something in common between them. The GCF of 2x and 10 is 2.
No. 3n isn't a factor of 3n + 7. The GCF of 3n + 7 and 9n is 1.
