18 is the LCM

#### Explanation:

Since the question is asking for the least common multiple, you factor out the 6 in 18 and 6. This gives you 6*3*1 as the LCM because you have factored out 6 and this is the GCF because there are no more common factors between 3 and 1. Since 6*3*1 equals 18, 18 is the LCM.
