How to find the greatest common factor - from TutaPoint.comby tutapoint34,903 views
Yes, this is an awesome method, however I came across two numbers that got me. 52 and 26. Using this method I keep getting "2" as being my GCF when the answer is "26". Please tell me what I'm doing wrong. Thanks

@ksluder From 52 and 26 you take out a 2, and have 26 and 13 left. You can take 13 out of both of those numbers. Multiply the 2 and the 13 and you get 26.
Glad this helps.
