Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 61/23,33/83,28/70,58/73
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 61,33,28,58
Greatest Common Factor of Numerators i.e. GCF of 61,33,28,58 is 1 .
LCM of Denominators means LCM of 23,83,70,73 as per the given fractions.
LCM of 23,83,70,73 is 9754990 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 61,33,28,58
∴ So GCF of numbers is 1 because of no common factors present between them.

1,2,29,58
Greatest Common Factor
We found the factors 61,33,28,58 . The biggest common factor number is the GCF number.
So the greatest common factor 61,33,28,58 is 1.
Lets's calculate LCM of 23,83,70,73
Given numbers has no common factors except 1. So, there LCM is their product i.e 9754990
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9754990
Therefore, the GCF of Fractions 61/23,33/83,28/70,58/73 is 1/9754990
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 23,83,70,73 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(23,83,70,73) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(23,83,70,73) x common factors =1 x 1 = 1
LCM(23,83,70,73) = ( 23 × 83 × 70 × 73 ) / 1
LCM(23,83,70,73) = 9754990 / 1
LCM(23,83,70,73) = 9754990
Here are some samples of GCF of Fractions calculations.
