Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 678/235,425/173
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 678,425
Greatest Common Factor of Numerators i.e. GCF of 678,425 is 1 .
LCM of Denominators means LCM of 235,173 as per the given fractions.
LCM of 235,173 is 40655 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 678,425
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 425 that divides 425 without a remainder.
1,5,17,25,85,425
Greatest Common Factor
We found the factors 678,425 . The biggest common factor number is the GCF number.
So the greatest common factor 678,425 is 1.
Lets's calculate LCM of 235,173
Given numbers has no common factors except 1. So, there LCM is their product i.e 40655
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/40655
Therefore, the GCF of Fractions 678/235,425/173 is 1/40655
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 235,173 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(235,173) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(235,173) x common factors =1 x 1 = 1
LCM(235,173) = ( 235 × 173 ) / 1
LCM(235,173) = 40655 / 1
LCM(235,173) = 40655
