How to find the GCF Greatest Common Factor

Learn a very simple way to find the greatest common factor. The GCF is the largest number that will divide into two or more numbers evenly. I like to use a factor tree and then a nice easy chart to keep everything organized.

I need help. What do you do when you have to find the gcf of a two numbers like 20 and 70 but you get two of the number 2 (in the column) and two of the number 5 (in the column)?

Thats not our method our method is countinuos division

[jimhill]

50+6 = 2
40+5 = 0
30+4 = 8

So the answer is obviously 6 😊
