Formula to find LCM of Fractions is

LCM = LCM of Numerators/HCF of Denominators

Step 1: Let suppose both the fractions are a/b and c/d

Step 2: LCM of two numbers is the lowest/smallest number that is a multiple of both

The HCF of two numbers is the largest number that is a fraction of both.

Example: Find the LCM of Fractions for 2/9, 8/21?


Given numbers are 2/9, 8/21

As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and HCF of Denominators

In the given fractions LCM of Numerators means LCM of 2, 8

Least Common Multiple of Numerators i.e. LCM of 2, 8 is 8.

HCF of Denominators means HCF of 9, 21 as per the given fractions.

HCF of 9, 21 is 3 as it is the largest common factor for both these numbers.

Thus LCM of Fractions = LCM of Numerators/HCF of Denominators = 8/3

Therefore the LCM of Fractions 2/9 and 8/ 21 is 8/3
