WebFactoring reverses that process. You start by finding the largest common factor. For 21x + 56, the largest common factor (GCF) = 7. We factor it out by putting 7 in front and by dividing each term by 7. 21x + 56 = 7 (21x/7 + 56/7) = 7 (3x+8) Now, see if you can factor you expression. I'll get you started. your GCF = 7.
