Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 2/21,643/92,798/95
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 2,643,798
Greatest Common Factor of Numerators i.e. GCF of 2,643,798 is 1 .
LCM of Denominators means LCM of 21,92,95 as per the given fractions.
LCM of 21,92,95 is 183540 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 2,643,798
∴ So GCF of numbers is 1 because of no common factors present between them.

1,2,3,6,7,14,19,21,38,42,57,114,133,266,399,798
Greatest Common Factor
We found the factors 2,643,798 . The biggest common factor number is the GCF number.
So the greatest common factor 2,643,798 is 1.
Lets's calculate LCM of 21,92,95
Given numbers has no common factors except 1. So, there LCM is their product i.e 183540
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/183540
Therefore, the GCF of Fractions 2/21,643/92,798/95 is 1/183540
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 21,92,95 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,92,95) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(21,92,95) x common factors =1 x 1 = 1
LCM(21,92,95) = ( 21 × 92 × 95 ) / 1
LCM(21,92,95) = 183540 / 1
LCM(21,92,95) = 183540
Here are some samples of GCF of Fractions calculations.
