**LCMs of Algebraic Expressions**

To find the LCM of two or more algebraic expressions, we factor them. Then

we use each factor the greatest number of times that it occurs in any one expression.

**Example**

12x , 16y, 8xyz = ?

12x = 2. 2. 3 .x

16y = 2 . 2 . 2 . 2 .y

8xyz = 2 . 2 . 2 . x . y .z

LCM = 2 . 2 . 2 . 2 . 3 . x . y . z = 48 xyz
