Find the least common multiple of 12 and 18
Break them down into primes:

    
 

12 has more 2 factors than 18 has, so the LCM will have the same
number of 2 factors as 12.  So the LCM has two 2 factors.

18 has more 3 factors than 12 has, so the LCM will have the same 
number of 3 factors as 18.  So the LCM has two 3 factors.

LCM=2*2*3*3 = 36
