Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 261/99,4647/843
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 261,4647
Greatest Common Factor of Numerators i.e. GCF of 261,4647 is 3 .
LCM of Denominators means LCM of 99,843 as per the given fractions.
LCM of 99,843 is 27819 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 261,4647
3 | 261, 4647 |
87, 1549 |
∴ So the GCF of the given numbers is 3 = 3

Factors of 4647
List of positive integer factors of 4647 that divides 4647 without a remainder.
1,3,1549,4647
Greatest Common Factor
We found the factors 261,4647 . The biggest common factor number is the GCF number.
So the greatest common factor 261,4647 is 3.
Lets's calculate LCM of 99,843
3 | 99, 843 |
33, 281 |
∴ So the LCM of the given numbers is 3 x 33 x 281 = 27819
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/27819
Therefore, the GCF of Fractions 261/99,4647/843 is 3/27819
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 99,843 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(99,843) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(99,843) x common factors =3 x 1 = 3
LCM(99,843) = ( 99 × 843 ) / 3
LCM(99,843) = 83457 / 3
LCM(99,843) = 27819
