here' how YOU can figure out the answer yourself...if you have a test/ quiz question with this type of problem on it, you won't be able to yahoo an answer.....
rewrite each term in its prime factors
"20x" is 2*2*5*x
"28x" is 2*2*7*x
the "common" factors are the ones in both terms
therefore 2*2*x

4X, because that can be divided into both those terms.
4X x 5 = 20X
4X x 7 = 28X
