Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 80/808,1810/1317
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 80,1810
Greatest Common Factor of Numerators i.e. GCF of 80,1810 is 10 .
LCM of Denominators means LCM of 808,1317 as per the given fractions.
LCM of 808,1317 is 1064136 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 80,1810
2 | 80, 1810 |
5 | 40, 905 |
8, 181 |
∴ So the GCF of the given numbers is 2 x 5 = 10

1,2,5,10,181,362,905,1810
Greatest Common Factor
We found the factors 80,1810 . The biggest common factor number is the GCF number.
So the greatest common factor 80,1810 is 10.
Lets's calculate LCM of 808,1317
Given numbers has no common factors except 1. So, there LCM is their product i.e 1064136
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/1064136
Therefore, the GCF of Fractions 80/808,1810/1317 is 10/1064136
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 808,1317 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(808,1317) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(808,1317) x common factors =1 x 1 = 1
LCM(808,1317) = ( 808 × 1317 ) / 1
LCM(808,1317) = 1064136 / 1
LCM(808,1317) = 1064136
Here are some samples of GCF of Fractions calculations.
