The GCF is 3w

Step-by-step explanation:

You have to find the GCF of

6w^3, 3w^2, 9w

You can start with 3. Then get:

6w^3/3 = 2w^3

3w^2/3 = w^2

9w/3 = 3w

The following factor is w. It has to have an exponent of one, as it the smallest exponent present in the 3 numbers:

2w^3/w = 2w

w^2/w = w

3w/w = 3

Expression:

6w^3 - 3w^2 - 9w= 3w(2w^2 - w - 3)

The GCF is 3w.
