It means absolutely nothing.
The C in GCF stabds for COMMON and you need more than one numbers or expressions (including polynomials) before there can be anything in common.
Divide the GCF into each to get the other factors.
The GCF is 2.
The GCF of 12x and 20x to the fourth power is 4x
The GCF of 20 and 4 is 4. That factors to 4(5x - 1)
4z2
The GCF is x6y3
2x3y2
