These numbers don't have a common dvisor, but if you are looking for the lowest common denominator, we need to break the numbers down into factors: 18=2*3*3; 16=2*2*2*2; 10=2*5; 20=2*2*5; 27=3*3*3. What's the most 2's we need? We need four. How many 3's? Three. How many 5's? Only one. Multiply 2*2*2*2*3*3*3*5=2160. Each of the numbers requires some of the numbers in the set of eight numbers we multiplied together, and there's no surplus. So they all divide into 2160.
