Question

180 is the LCM of 12 and what?

Answer 1

It’s 90 because you can’t divide 90 by 12 evenly so you would go to the next multiple of 90 which would be 180 and 12 can go into 180 evenly making 180 the LCM

If it were 15 like the other person said the LCM would be 60

Answer 2

To get the other number

divide 12 from 180

180/12 = 15

The LCM is 12 and 15

hope this helps
