Question

LCD of 12 and 18
A) 36
B) 42
C) 12
D) 6

Answer 1

LCM means Least Common Multiple. That means in this case, we need to look for a number which would be multiple of both 12 and 18. There are different ways to find it. One way would be you expand 12 by its smallest factors like

12 = 2 x 2 x 3

And 18 can be written by its smallest factors as 18 = 2 x 3 x 3

Now, we in order to find the LCM of 12 and 18 , we need to take the common factors only once(Factors in bold) and also the uncommon ones.

So the LCM will be like this = 2 x 3 x 2 x 3 = 36.

Another way of finding the LCM is as follows
