## How to calculate the LCD of a number?

In the simplest case we have just two numbers, a and b, and we can use the notation LCD (a, b). The LCD is the least common multiple (LCM) of the fractions’ denominators. The least common denominator calculator will help you find the LCD you needs before adding, subtracting, or comparing fractions.

**Which is the least common denominator in LCD calculator?**

Common denominator calculator will give the LCD of two or more different or unequal denominators of fractions. Output: The least common denominator is an integer number. The common denominator calculator determines the least common denominator as the least common multiple of two or more integers using the prime factorization.
