Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 431/39,9912/439
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 431,9912
Greatest Common Factor of Numerators i.e. GCF of 431,9912 is 1 .
LCM of Denominators means LCM of 39,439 as per the given fractions.
LCM of 39,439 is 17121 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 431,9912
∴ So GCF of numbers is 1 because of no common factors present between them.

Greatest Common Factor
We found the factors 431,9912 . The biggest common factor number is the GCF number.
So the greatest common factor 431,9912 is 1.
Lets's calculate LCM of 39,439
Given numbers has no common factors except 1. So, there LCM is their product i.e 17121
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/17121
Therefore, the GCF of Fractions 431/39,9912/439 is 1/17121
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 39,439 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,439) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(39,439) x common factors =1 x 1 = 1
LCM(39,439) = ( 39 × 439 ) / 1
LCM(39,439) = 17121 / 1
LCM(39,439) = 17121
