To find the Least Common Denominator (LCD) of two or more fractions, follow these steps:

1. **Identify the Denominators**: Write down the denominators of all the fractions you are working with.

2. **List the Multiples**: Find the multiples of each denominator. Start with the first denominator and list its multiples until you find a common multiple with the other denominators. Do the same for the other denominators.

3. **Identify the Least Common Multiple (LCM)**: Among the multiples you listed, identify the smallest number that appears in all the lists. This number is the Least Common Multiple (LCM) of the denominators.

4. **The LCM is the LCD**: Once you've found the LCM, it is also the Least Common Denominator (LCD) for the fractions you're working with.

Let's illustrate with an example:

Suppose you have the fractions 1/3 and 2/5.

1. The denominators are 3 and 5.

2. List the multiples:

- For 3: 3, 6, 9, 12, 15, ...

- For 5: 5, 10, 15, 20, ...

3. The LCM is 15 because it's the smallest number that appears in both lists.

4. So, the LCD of 1/3 and 2/5 is 15.

Remember, if you're dealing with more than two fractions, you still follow the same steps but consider all the denominators involved to find the LCD.
