Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 891/878,1257/199
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 891,1257
Greatest Common Factor of Numerators i.e. GCF of 891,1257 is 3 .
LCM of Denominators means LCM of 878,199 as per the given fractions.
LCM of 878,199 is 174722 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 891,1257
3 | 891, 1257 |
297, 419 |
∴ So the GCF of the given numbers is 3 = 3

Factors of 1257
List of positive integer factors of 1257 that divides 1257 without a remainder.
1,3,419,1257
Greatest Common Factor
We found the factors 891,1257 . The biggest common factor number is the GCF number.
So the greatest common factor 891,1257 is 3.
Lets's calculate LCM of 878,199
Given numbers has no common factors except 1. So, there LCM is their product i.e 174722
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/174722
Therefore, the GCF of Fractions 891/878,1257/199 is 3/174722
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 878,199 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(878,199) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(878,199) x common factors =1 x 1 = 1
LCM(878,199) = ( 878 × 199 ) / 1
LCM(878,199) = 174722 / 1
LCM(878,199) = 174722
Here are some samples of GCF of Fractions calculations.
