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.

Find the least common denominator for fractions with denominators 9 12 and 16?
The least common denominator is 144.
How do you find the least common denominator of a set of unlike fractions?
To find the least common denominator of a set of unlike fractions, you first need to list the prime factors of each denominator. Then, identify the highest power of each prime factor that appears in any of the denominators. Finally, multiply these highest powers together to find the least common multiple, which will be the least common denominator for the fractions.
