Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 83/13,33/56,61/11,109/15
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 83,33,61,109
Greatest Common Factor of Numerators i.e. GCF of 83,33,61,109 is 1 .
LCM of Denominators means LCM of 13,56,11,15 as per the given fractions.
LCM of 13,56,11,15 is 120120 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 83,33,61,109
∴ So GCF of numbers is 1 because of no common factors present between them.

1,109
Greatest Common Factor
We found the factors 83,33,61,109 . The biggest common factor number is the GCF number.
So the greatest common factor 83,33,61,109 is 1.
Lets's calculate LCM of 13,56,11,15
Given numbers has no common factors except 1. So, there LCM is their product i.e 120120
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/120120
Therefore, the GCF of Fractions 83/13,33/56,61/11,109/15 is 1/120120
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 13,56,11,15 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(13,56,11,15) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(13,56,11,15) x common factors =1 x 1 = 1
LCM(13,56,11,15) = ( 13 × 56 × 11 × 15 ) / 1
LCM(13,56,11,15) = 120120 / 1
LCM(13,56,11,15) = 120120
