How to find GCF of Fractions?

Formula to find GCF of Fractions is

GCF = GCF of Numerators/LCM of Denominators

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

Step 2: GCF 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 GCF of Fractions for 2/9, 8/21?


Given numbers are 2/9, 8/21

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

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

Greatest Common Factor of Numerators i.e. GCF of 2, 8 is 2.

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

LCM of 9, 21 is 63 as it is the smallest common factor for both these numbers.

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/63

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