Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 256/41,861/7731
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 256,861
Greatest Common Factor of Numerators i.e. GCF of 256,861 is 1 .
LCM of Denominators means LCM of 41,7731 as per the given fractions.
LCM of 41,7731 is 316971 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 256,861
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 256 that divides 256 without a remainder.
1,2,4,8,16,32,64,128,256
Factors of 861
List of positive integer factors of 861 that divides 861 without a remainder.
1,3,7,21,41,123,287,861
Greatest Common Factor
We found the factors 256,861 . The biggest common factor number is the GCF number.
So the greatest common factor 256,861 is 1.
Lets's calculate LCM of 41,7731
Given numbers has no common factors except 1. So, there LCM is their product i.e 316971
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/316971
Therefore, the GCF of Fractions 256/41,861/7731 is 1/316971
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 41,7731 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(41,7731) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(41,7731) x common factors =1 x 1 = 1
LCM(41,7731) = ( 41 × 7731 ) / 1
LCM(41,7731) = 316971 / 1
LCM(41,7731) = 316971
