Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 479/398,2068/787
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 479,2068
Greatest Common Factor of Numerators i.e. GCF of 479,2068 is 1 .
LCM of Denominators means LCM of 398,787 as per the given fractions.
LCM of 398,787 is 313226 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 479,2068
∴ So GCF of numbers is 1 because of no common factors present between them.

1,479
Factors of 2068
List of positive integer factors of 2068 that divides 2068 without a remainder.
1,2,4,11,22,44,47,94,188,517,1034,2068
Greatest Common Factor
We found the factors 479,2068 . The biggest common factor number is the GCF number.
So the greatest common factor 479,2068 is 1.
Lets's calculate LCM of 398,787
Given numbers has no common factors except 1. So, there LCM is their product i.e 313226
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/313226
Therefore, the GCF of Fractions 479/398,2068/787 is 1/313226
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 398,787 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(398,787) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(398,787) x common factors =1 x 1 = 1
LCM(398,787) = ( 398 × 787 ) / 1
LCM(398,787) = 313226 / 1
LCM(398,787) = 313226
