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
