Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 18/11,31/47,66/93,57/79
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 18,31,66,57
Greatest Common Factor of Numerators i.e. GCF of 18,31,66,57 is 1 .
LCM of Denominators means LCM of 11,47,93,79 as per the given fractions.
LCM of 11,47,93,79 is 3798399 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 18,31,66,57
∴ So GCF of numbers is 1 because of no common factors present between them.

1,31
Factors of 66
List of positive integer factors of 66 that divides 66 without a remainder.
1,2,3,6,11,22,33,66
Factors of 57
List of positive integer factors of 57 that divides 57 without a remainder.
1,3,19,57
Greatest Common Factor
We found the factors 18,31,66,57 . The biggest common factor number is the GCF number.
So the greatest common factor 18,31,66,57 is 1.
Lets's calculate LCM of 11,47,93,79
Given numbers has no common factors except 1. So, there LCM is their product i.e 3798399
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3798399
Therefore, the GCF of Fractions 18/11,31/47,66/93,57/79 is 1/3798399
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 11,47,93,79 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(11,47,93,79) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(11,47,93,79) x common factors =1 x 1 = 1
LCM(11,47,93,79) = ( 11 × 47 × 93 × 79 ) / 1
LCM(11,47,93,79) = 3798399 / 1
LCM(11,47,93,79) = 3798399
Here are some samples of GCF of Fractions calculations.
