Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 981/711,378/764
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 981,378
Greatest Common Factor of Numerators i.e. GCF of 981,378 is 9 .
LCM of Denominators means LCM of 711,764 as per the given fractions.
LCM of 711,764 is 543204 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 981,378
3 | 981, 378 |
3 | 327, 126 |
109, 42 |
∴ So the GCF of the given numbers is 3 x 3 = 9

Factors of 378
List of positive integer factors of 378 that divides 378 without a remainder.
1,2,3,6,7,9,14,18,21,27,42,54,63,126,189,378
Greatest Common Factor
We found the factors 981,378 . The biggest common factor number is the GCF number.
So the greatest common factor 981,378 is 9.
Lets's calculate LCM of 711,764
Given numbers has no common factors except 1. So, there LCM is their product i.e 543204
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/543204
Therefore, the GCF of Fractions 981/711,378/764 is 9/543204
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 711,764 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(711,764) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(711,764) x common factors =1 x 1 = 1
LCM(711,764) = ( 711 × 764 ) / 1
LCM(711,764) = 543204 / 1
LCM(711,764) = 543204
Here are some samples of GCF of Fractions calculations.
