WebYou 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. Hope this helps. ( 4 votes) Flag Katie Thomas 7 years ago WebStep 1: List the prime factors of each number. Step 2: Draw a circle around the prime factors that are common to all lists. Step 3: Multiply the numbers which you have drawn a circle around them. The answer is the Greatest Common Factor (GCF) between those numbers. Note: If there are no common prime factors, the GCF (Greatest Common Factor) is 1 1.
