Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 855/37,478/1285
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 855,478
Greatest Common Factor of Numerators i.e. GCF of 855,478 is 1 .
LCM of Denominators means LCM of 37,1285 as per the given fractions.
LCM of 37,1285 is 47545 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 855,478
∴ So GCF of numbers is 1 because of no common factors present between them.

1,3,5,9,15,19,45,57,95,171,285,855
Factors of 478
List of positive integer factors of 478 that divides 478 without a remainder.
1,2,239,478
Greatest Common Factor
We found the factors 855,478 . The biggest common factor number is the GCF number.
So the greatest common factor 855,478 is 1.
Lets's calculate LCM of 37,1285
Given numbers has no common factors except 1. So, there LCM is their product i.e 47545
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/47545
Therefore, the GCF of Fractions 855/37,478/1285 is 1/47545
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 37,1285 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(37,1285) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(37,1285) x common factors =1 x 1 = 1
LCM(37,1285) = ( 37 × 1285 ) / 1
LCM(37,1285) = 47545 / 1
LCM(37,1285) = 47545
