Least common denominator or LCD has 2 or more denominators are basically the least whole number which is divisible by both of the denominators. Least Common Denominator Calculator (LCD Calculator or lcd finder) takes two fractions in the simplest form and calculates the least common denominator for them.You just have to enter the given two fractions in the block provided and get the least common denominator instantly.

Note down the denominator of each fraction.

For those denominators find out the lcm or least common multiple. This would be the least common denominator.

Find the least common denominator for the given numbers $\frac{1}{8}$ + $\frac{1}{16}$

**Step 1 :**The given denominators are 8 and 16

**Step 2 :**The multiples of 8: 8, 16, 24, 32, 40 and so on...

The multiples of 16: 16, 32, 48 and so on...

Therefore you may notice for both of the denominators the least common number is 16.

**Answer :**Hence, the least common denominator of $\frac{1}{8}$ and $\frac{1}{16}$ are 16.

Find the least common denominator for the given numbers $\frac{1}{4}$ + $\frac{1}{9}$

**Step 1 :**The given denominators are 4 and 9

**Step 2 :**The multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 38 and so on...

The multiples of 9: 9, 18, 27, 36, 45 and so on...

Therefore you may notice for both of the denominators the least common number is 36.**Answer :**Hence, the least common denominator of $\frac{1}{4}$ and $\frac{1}{9}$ is 36.
