Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 427/39,704/31,120/32
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 427,704,120
Greatest Common Factor of Numerators i.e. GCF of 427,704,120 is 1 .
LCM of Denominators means LCM of 39,31,32 as per the given fractions.
LCM of 39,31,32 is 38688 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 427,704,120
∴ So GCF of numbers is 1 because of no common factors present between them.

1,2,3,4,5,6,8,10,12,15,20,24,30,40,60,120
Greatest Common Factor
We found the factors 427,704,120 . The biggest common factor number is the GCF number.
So the greatest common factor 427,704,120 is 1.
Lets's calculate LCM of 39,31,32
Given numbers has no common factors except 1. So, there LCM is their product i.e 38688
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/38688
Therefore, the GCF of Fractions 427/39,704/31,120/32 is 1/38688
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 39,31,32 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,31,32) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(39,31,32) x common factors =1 x 1 = 1
LCM(39,31,32) = ( 39 × 31 × 32 ) / 1
LCM(39,31,32) = 38688 / 1
LCM(39,31,32) = 38688
