How do you find LCD?

In order to use the greatest common factor to solve the problem, you must first multiply the two denominators together. Divide this product by the GCF. After finding the product of the two denominators, divide that product by the GCF you found previously. This number will be your least common denominator (LCD).

Whats the LCD of 5 and 15?

15
The LCM of 5 and 15 is 15. To find the least common multiple of 5 and 15, we need to find the multiples of 5 and 15 (multiples of 5 = 5, 10, 15, 20; multiples of 15 = 15, 30, 45, 60) and choose the smallest multiple that is exactly divisible by 5 and 15, i.e., 15.

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.
