Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 791/89,9090/615
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 791,9090
Greatest Common Factor of Numerators i.e. GCF of 791,9090 is 1 .
LCM of Denominators means LCM of 89,615 as per the given fractions.
LCM of 89,615 is 54735 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 791,9090
∴ So GCF of numbers is 1 because of no common factors present between them.

Greatest Common Factor
We found the factors 791,9090 . The biggest common factor number is the GCF number.
So the greatest common factor 791,9090 is 1.
Lets's calculate LCM of 89,615
Given numbers has no common factors except 1. So, there LCM is their product i.e 54735
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/54735
Therefore, the GCF of Fractions 791/89,9090/615 is 1/54735
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 89,615 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(89,615) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(89,615) x common factors =1 x 1 = 1
LCM(89,615) = ( 89 × 615 ) / 1
LCM(89,615) = 54735 / 1
LCM(89,615) = 54735
