Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 421/123,3908/719
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 421,3908
Greatest Common Factor of Numerators i.e. GCF of 421,3908 is 1 .
LCM of Denominators means LCM of 123,719 as per the given fractions.
LCM of 123,719 is 88437 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 421,3908
∴ So GCF of numbers is 1 because of no common factors present between them.

1,421
Factors of 3908
List of positive integer factors of 3908 that divides 3908 without a remainder.
1,2,4,977,1954,3908
Greatest Common Factor
We found the factors 421,3908 . The biggest common factor number is the GCF number.
So the greatest common factor 421,3908 is 1.
Lets's calculate LCM of 123,719
Given numbers has no common factors except 1. So, there LCM is their product i.e 88437
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/88437
Therefore, the GCF of Fractions 421/123,3908/719 is 1/88437
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 123,719 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(123,719) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(123,719) x common factors =1 x 1 = 1
LCM(123,719) = ( 123 × 719 ) / 1
LCM(123,719) = 88437 / 1
LCM(123,719) = 88437
