**All about Least Common Denominator**

Let's wait no further and learn all the Basics like Denominator, Common Denominator, Least Common Denominator to know about the concept easily.

**What is Denominator?**

The denominator is usually the bottom part of a fraction. It shows how many equal parts the item is divided.

**Example:** 3/4 Here 4 is the denominator and the item is divided into 4 equal parts.

**What is the Common Denominator?**

If the denominators of two or more fractions are the same then they are said to have common Denominators.

**Example:** 2/5 + 3/5

In the given fractions both of them are having the same or common denominators i.e. 5

**Definition of Least Common Denominator**

The Least Common Denominator is the smallest number of all the common multiples of denominators if two or more fractions are given. Least Common Denominator in short is represented as LCD.

**Example:** What is the LCD of 2/9+ 3/4?

As both the fractions have different denominators. Firstly find the common multiples of both the denominators

Multiples of 9 are 9, 18, 27, **36**, 45, 54, 63, 72, 81

Multiples of 4 are 4, 8, 12, 16, 20, 24, 28, 32, **36**, 40, 44

Common Multiple is 36

Now that we found the Least Common Multiple let's express it

= 2/9+3/4

= (2/9)*(4/4)+(3/4)*(9/9)

= (8/36)+(27/36)

=35/36

**Why LCD is useful?**

Least Common Denominator for Fractions is useful to determine the result as a part of the whole. You can use the Concept of LCD to solve numerous problems easily and quickly.

**Other Names of Least Common Denominator**

The acronym of the Least Common Denominator is LCD. It is also known as the Lowest Common Denominator(LCD), Lowest Common Factor(LCF), or Least Common Multiple(LCM).
