Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 84/67,18/57,563/68
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 84,18,563
Greatest Common Factor of Numerators i.e. GCF of 84,18,563 is 1 .
LCM of Denominators means LCM of 67,57,68 as per the given fractions.
LCM of 67,57,68 is 259692 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 84,18,563
∴ So GCF of numbers is 1 because of no common factors present between them.

Greatest Common Factor
We found the factors 84,18,563 . The biggest common factor number is the GCF number.
So the greatest common factor 84,18,563 is 1.
Lets's calculate LCM of 67,57,68
Given numbers has no common factors except 1. So, there LCM is their product i.e 259692
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/259692
Therefore, the GCF of Fractions 84/67,18/57,563/68 is 1/259692
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 67,57,68 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(67,57,68) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(67,57,68) x common factors =1 x 1 = 1
LCM(67,57,68) = ( 67 × 57 × 68 ) / 1
LCM(67,57,68) = 259692 / 1
LCM(67,57,68) = 259692
