The Lowest Common Multiple, by definition,
is the smallest number that each numberin
question will divide into.  As Patrick said, look
the largest number in question, list a few multiples...
Do so until you find the first one the smaller
numbers will divide into.
 
Example:  Find LCM of 12 and 15.
 
Multiples of 15: 15, 30, 45, 60
Multiples of 12:  12, 24, 36, 48, 60
 
LCM = 60
That is the smallest. umber that both12 and 15
divide into evenly.
