The GCF is 5x
The GCF is 6.
x2 + 8xy + 15y2 = (x + 3y) (x + 5y)
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. You have only one expression in the question!
The greatest common factor is the biggest number that multiplies into making 15w and 21.15w = 3 • 5 • w21 = 3 • 7So the GCF is 3. We simply pull it out from the problem.3(5w+7)
