Question

How can i find out the LCM of 6, 12, 15?

Answer 1

you have to think of a number that is able to go into 6, 12, and 15

Answer 2

for example, does 2 work?

6/2 = 3 so 2 works with 6
12-2=6 so 2 works with 12
15/2=7.5 so 2 is not a factor of 15

therefore you need to find another number

Answer 3

then try 3, i know 3 is the answer because 3 is able to go evenly into all three numbers

Answer 4

basically it's trial and error but there are methods like prime factorization, decomposition method (i think that's what it was called), etc.

Answer 5

ope, I don't remember that, I can just look at those numbers and say that 3 is the answer

Answer 6

I need to find the answer not the factor.

Answer 7

oh shoottttt, my bad, I read it wrong, I thought it said LCD.....awkkk
