Find the GCF of 8d−20 .

Answer 1

To find the greatest common factor (GCF) of 8d−20, we need to determine the largest factor that both terms have in common.

First, let's factor out any common factors between 8 and −20. The factors of 8 are 1, 2, 4, and 8. The factors of −20 are 1, 2, 4, 5, 10, and 20. The common factors are 1, 2, and 4.

Now let's consider the variable part, d. Since d is not common to both terms, we do not include it in our GCF.

Therefore, the GCF of 8d−20 is 4.
