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 6940,1300
Greatest Common Factor of Numerators i.e. GCF of 6940,1300 is 20 .
LCM of Denominators means LCM of 515,278 as per the given fractions.
LCM of 515,278 is 143170 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 6940,1300
2 | 6940, 1300 |
2 | 3470, 650 |
5 | 1735, 325 |
347, 65 |
∴ So the GCF of the given numbers is 2 x 2 x 5 = 20

Greatest Common Factor
We found the factors 6940,1300 . The biggest common factor number is the GCF number.
So the greatest common factor 6940,1300 is 20.
Lets's calculate LCM of 515,278
Given numbers has no common factors except 1. So, there LCM is their product i.e 143170
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/143170
Therefore, the GCF of Fractions 6940/515,1300/278 is 20/143170
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 515,278 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(515,278) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(515,278) x common factors =1 x 1 = 1
LCM(515,278) = ( 515 × 278 ) / 1
LCM(515,278) = 143170 / 1
LCM(515,278) = 143170
Here are some samples of GCF of Fractions calculations.
