Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 77/971,198/556
Formula to find GCF of Fractions is
GCF = GCF of Numerators/LCM of Denominators
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 77,198
Greatest Common Factor of Numerators i.e. GCF of 77,198 is 11 .
LCM of Denominators means LCM of 971,556 as per the given fractions.
LCM of 971,556 is 539876 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 77,198
11 | 77, 198 |
7, 18 |
∴ So the GCF of the given numbers is 11 = 11

1,7,11,77
Factors of 198
List of positive integer factors of 198 that divides 198 without a remainder.
1,2,3,6,9,11,18,22,33,66,99,198
Greatest Common Factor
We found the factors 77,198 . The biggest common factor number is the GCF number.
So the greatest common factor 77,198 is 11.
Lets's calculate LCM of 971,556
Given numbers has no common factors except 1. So, there LCM is their product i.e 539876
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/539876
Therefore, the GCF of Fractions 77/971,198/556 is 11/539876
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 971,556 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(971,556) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(971,556) x common factors =1 x 1 = 1
LCM(971,556) = ( 971 × 556 ) / 1
LCM(971,556) = 539876 / 1
LCM(971,556) = 539876
Here are some samples of GCF of Fractions calculations.
