What is the Common Denominator?

If you consider a fraction, then the lower part of the fraction is called the denominator. If 2 or more fractions have the same denominator, then it is called the common denominator. There are different methods to calculate the denominator. As addition & subtraction of fractions is not possible without the common denominators of given fractions.

Greatest Common Divisor & Least Common Multiple Calculator

Greatest common divisor is the greatest number which can divide all the given numbers with no remainder and the Least common multiple is the smallest number which can be divisible by all the given numbers completely. There is a relation between GCD & LCM. The product of GCD & LCM is always equal to the product of a given set of numbers.

What is the Easiest Way to Find the Lowest Common Denominator? 

Here are the steps to calculate the lowest common denominator. Method of cross multiplication is used here for calculation which is one the easiest & basic methods for calculation:

  1. Consider the given set of fractions & simplify them if necessary.
  2. Multiply the numerator & denominator of a 1st fraction with the denominator of the 2nd fraction.

Solved Example Finding the Least Common Denominator


 Find the Least Common Denominator of fractions 3/5 & 2/3.


Given fractions are 3/5 & 2/3.

Now, we will multiply the fractions with the denominators of another fraction.

So, 3/5 = (3 x 3) / (5 x 3) = 9 / 15

& 2/3 = (2 x 5) / (3 x 5) = 10 / 15

 So, the least common denominator for the fractions 3/5 & 2/3 is 15.
