Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 810/45,2690/853
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 810,2690
Greatest Common Factor of Numerators i.e. GCF of 810,2690 is 10 .
LCM of Denominators means LCM of 45,853 as per the given fractions.
LCM of 45,853 is 38385 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 810,2690
2 | 810, 2690 |
5 | 405, 1345 |
81, 269 |
∴ So the GCF of the given numbers is 2 x 5 = 10

1,2,5,10,269,538,1345,2690
Greatest Common Factor
We found the factors 810,2690 . The biggest common factor number is the GCF number.
So the greatest common factor 810,2690 is 10.
Lets's calculate LCM of 45,853
Given numbers has no common factors except 1. So, there LCM is their product i.e 38385
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/38385
Therefore, the GCF of Fractions 810/45,2690/853 is 10/38385
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 45,853 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(45,853) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(45,853) x common factors =1 x 1 = 1
LCM(45,853) = ( 45 × 853 ) / 1
LCM(45,853) = 38385 / 1
LCM(45,853) = 38385
Here are some samples of GCF of Fractions calculations.
