Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 357/715,557/643
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 357,557
Greatest Common Factor of Numerators i.e. GCF of 357,557 is 1 .
LCM of Denominators means LCM of 715,643 as per the given fractions.
LCM of 715,643 is 459745 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 357,557
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 357 that divides 357 without a remainder.
1,3,7,17,21,51,119,357
Factors of 557
List of positive integer factors of 557 that divides 557 without a remainder.
1,557
Greatest Common Factor
We found the factors 357,557 . The biggest common factor number is the GCF number.
So the greatest common factor 357,557 is 1.
Lets's calculate LCM of 715,643
Given numbers has no common factors except 1. So, there LCM is their product i.e 459745
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/459745
Therefore, the GCF of Fractions 357/715,557/643 is 1/459745
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 715,643 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(715,643) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(715,643) x common factors =1 x 1 = 1
LCM(715,643) = ( 715 × 643 ) / 1
LCM(715,643) = 459745 / 1
LCM(715,643) = 459745
