Question

lcm 16 and 12

Answer 1

Least common multiple of 12 and 16 is 48

12 = 2 x 2 x 3
16 = 2 x 2 x 2 x 2
----------------------
The LCM of 16,12 is:
2 x 2 x 2 x 2 x 3
= 48
48

Process:
4x3=12
4x4=16

4x3x4=48-To find the least common multiple for a number you will have to write all or some of the multiples for both of your numbers,then you have to find 2 numbers that are the same in both pairs,then you find if there are more pairs that you listed then if they are less,you use those,even lower, you use those 2 pairs of numbers.For Example, when you are trying to find the LCM ( Least common multiple) of 2,3 you do as said then you find the 2 number that are lest than the other numbers then you will have the LCM of those 2 numbers.

Answer 2

16 = 2*2*2*2

12 = 2*2*3

Thus,
LCM(16,12) = 2*2*2*2*3 = 48
