You can also do this for the LCM, all you have to do is multiply everything and not just the nos. on the sides :)

Danke

lol this is the only video on youtube that i found who explains well how to do these , the other methods were confusing with larger numbers

[42jemini]

Thanks for showing that last one. I have a habit of avoiding anything that involves a lot of writting, so it required you showing something I could not do in my head (like I did with the first 2 in about 2 seconds each) in order to get me to actually think I might use this at some point.

[starzified5]

Thankyou you were so helpful to me and my math. Thanks for taking to do this ur so nice.

[ksluder]

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

[Nancyfootehigley]

@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.

[ksluder]

@Nancyfootehigley Thanks a bunch!!!
