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.

When comparing fractions you must find a common denominator; by finding the least common denominator it will keep the numbers (numerators and denominator) smaller .

The least common denominator is 144.

Pick two of the fractions and find the Least Common Multiple of those two denominators. Then take that number, and find the Least Common Multiple between that and the third denominator. This number will be the Least Common Denominator between the three fractions.If you don't care to find the Least common denominator, then just take the three denominators, and multiply them together.

That's one fraction. You need at least two to find something in common between them.

The way that you can find the least common denominator is by first multiplying the 2 bottom numbers and whatever the product is that is your common denominator. to find the smallest one, you have to keep dividing it till it is in counting order or there is an odd number.
