Say there's 2/3 and 1/2, it's called Least Common Denominator, so you need to look at the denominators which are 3 and 2.

Now list the multiples:

3: 1, 3, 6...

2: 1, 2, 4, 6...

As you can see both of them go into 6 the least amount of times because it's the one that they both can multiply.

Denominators are whole numbers. Find it just like the LCM.

Example: 1/30 and 1/42

Factor them.

2 x 3 x 5 = 30

2 x 3 x 7 = 42

Combine the factors, eliminating duplicates.

2 x 3 x 5 x 7 = 210, the LCD
