Question

Find the greatest common factor of 8d - 20

Answer 1

To find the greatest common factor (GCF) of 8d - 20, we need to factorize the expression:

8d - 20

First, we can factor out the greatest common factor of the coefficients, which is 4:

4(2d - 5)

Now we can see that there are no other common factors between the numerical coefficient (2d - 5) and the variable (d). Therefore, the GCF of 8d - 20 is simply 4.
