Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 345/691,1211/7105
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 345,1211
Greatest Common Factor of Numerators i.e. GCF of 345,1211 is 1 .
LCM of Denominators means LCM of 691,7105 as per the given fractions.
LCM of 691,7105 is 4909555 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 345,1211
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 345 that divides 345 without a remainder.
1,3,5,15,23,69,115,345
Factors of 1211
List of positive integer factors of 1211 that divides 1211 without a remainder.
1,7,173,1211
Greatest Common Factor
We found the factors 345,1211 . The biggest common factor number is the GCF number.
So the greatest common factor 345,1211 is 1.
Lets's calculate LCM of 691,7105
Given numbers has no common factors except 1. So, there LCM is their product i.e 4909555
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4909555
Therefore, the GCF of Fractions 345/691,1211/7105 is 1/4909555
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 691,7105 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(691,7105) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(691,7105) x common factors =1 x 1 = 1
LCM(691,7105) = ( 691 × 7105 ) / 1
LCM(691,7105) = 4909555 / 1
LCM(691,7105) = 4909555
