Several methods are possible. First, you can just multiply two numbers to get a common denominator, and not worry whether it is the least such common denominator, or not. To actually get the LCD, use one of the following methods:

(1) Take consecutive multiples of the largest number and see which of them is divisible by the other one.

(2) Use prime factorization.

(3) Use Euclid's algorithm. This one is the most efficient method for larger numbers.
