If you start from the set D, the problem is much easier. The numbers divisible by 6 from 1 to 12 are 6 and 12 which are both in between 1 and 18. The intersection of C and D are the numbers shared by the two sets so the answer is {6,12}

I guess you can technically divide any number from 1 to 12 by 6 but assume this question means with no remainder.
