For 2, i would approach it like this:

The question is asking for the smallest integer x, that has 12 and 81 as a divisor. By definition, this question is asking for the least common multiple of 12 and 81.
The first step is to find the greatest common factor of 12 and 81, which is 3. Divide 3 into both numbers and you get 4 and 27. Multiply. 3427=324
