Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 102/257,3515/1147
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 102,3515
Greatest Common Factor of Numerators i.e. GCF of 102,3515 is 1 .
LCM of Denominators means LCM of 257,1147 as per the given fractions.
LCM of 257,1147 is 294779 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 102,3515
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 102 that divides 102 without a remainder.
1,2,3,6,17,34,51,102
Factors of 3515
List of positive integer factors of 3515 that divides 3515 without a remainder.
1,5,19,37,95,185,703,3515
Greatest Common Factor
We found the factors 102,3515 . The biggest common factor number is the GCF number.
So the greatest common factor 102,3515 is 1.
Lets's calculate LCM of 257,1147
Given numbers has no common factors except 1. So, there LCM is their product i.e 294779
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/294779
Therefore, the GCF of Fractions 102/257,3515/1147 is 1/294779
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 257,1147 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(257,1147) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(257,1147) x common factors =1 x 1 = 1
LCM(257,1147) = ( 257 × 1147 ) / 1
LCM(257,1147) = 294779 / 1
LCM(257,1147) = 294779
