Question

Factor the following expression using the GCF.4dr – 16rr(4 d – 16)2 r(2 d – 8)4( dr – 4 r)4 r( d – 4)

Answer 1

Given:

An expression

$4dr-16r$

Required:

Factor the given expression using the GCF.

Explanation:

We know that the GCF is the highest number that divides exactly two or more numbers.

The given expression is:

$4dr-16r$

The highest number in both the given number is 4r.

So take out common 4r from the given expression.

$4dr-16r=4r(d-4)$

Thus the factors of the given expression are 4r(d-4).
