Yet another reason our public schools are in shambles:  The ladder method of LCM. Park that right next to still writing in caligraphy and cursive writing. Mindless activity.

[Sojouku]

This is useful, but it doesnt work if there are 3 numbers.

[DAiSYSandTHiNGS]

@Sojouku just find a number that is divisible by the three numbers :P

[1Romogirl]

Thanks so much!!!! Because of your awesome ladder method I finally get LCM. You have the best explanation of how to do LCM problems.

[roxygirlallie]

very, very descriptive! thank you soooo much!

[trollmaker]

If the number is prime, then by definition, it cannot be divide by any number besides its self and one. This is what she does when she says that one is the only number that goes into both numbers at the bottom of her ladder, making writing and multiplying by one irrelevant to the problem.

[BrittKayBritt]

you cant do example two [the outside numbers are supposed to be prime.] well thats what my math teacher tauttt meee. sooooo yeah kinda u did it wrong but idk .

[Ingamer101]

What if a number is prime?

[Ingamer101]

What if it's prime??

[WeAreTheDynamicDuo]

[TheTeeHeeXD]

[kding214]

Great! Thank You

[Teacherdude24]

Yes, this method works with three numbers. It really works for any amount of numbers.

[AnabellQ]

Does this method work with three numbers?

[nacetroy]

Thank you for this great explanation, very nice and neat way of finding the LCM. I'm going to share it with my teacher.
