GAWD im typing random things into my calc and it looks like the only way to find it is to multiply them all together (: so
12 * 32 * 42 = 16128

Answer 9

yep im sure do you want to know how to find it?

Answer 10

please

Answer 11

yes

Answer 12

ok you can start by taking the largest integer in the argument. You multiply it by 1 and see if the other numbers divide evenly into the result. If they do you are done and 1*largest is your least common multiple. If not you multiply by 2 and check if the other two divide evenly in. You repeat this until you find an integer that all arguments divide evenly into, and the first integer that this happens for is your least common multiple. So in your example 42*16 is the first integer multiple of the largest number that all arguments divide evenly into.
