Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 385/245,247/179
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 385,247
Greatest Common Factor of Numerators i.e. GCF of 385,247 is 1 .
LCM of Denominators means LCM of 245,179 as per the given fractions.
LCM of 245,179 is 43855 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 385,247
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 385 that divides 385 without a remainder.
1,5,7,11,35,55,77,385
Factors of 247
List of positive integer factors of 247 that divides 247 without a remainder.
1,13,19,247
Greatest Common Factor
We found the factors 385,247 . The biggest common factor number is the GCF number.
So the greatest common factor 385,247 is 1.
Lets's calculate LCM of 245,179
Given numbers has no common factors except 1. So, there LCM is their product i.e 43855
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/43855
Therefore, the GCF of Fractions 385/245,247/179 is 1/43855
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 245,179 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(245,179) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(245,179) x common factors =1 x 1 = 1
LCM(245,179) = ( 245 × 179 ) / 1
LCM(245,179) = 43855 / 1
LCM(245,179) = 43855
