The ratio of LCM to GCF is 6:1, so

That means one of the two numbers has a factor of 6 that the other number does not. So if one of the numbers is 18, then there are two possible pairs of numbers:

(1) 18 and 18/6=3. LCM(18,3)=18; GCF(3,18)=3; 18:3=6:1

(2) 18 and 18*6=108. LCM(18,108)=108; GCF(18,108)=18; 108:18=6:1

ANSWERS: There are two possible numbers for the LCM -- 18 and 108
