Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 17/83,99/64,408/85
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 17,99,408
Greatest Common Factor of Numerators i.e. GCF of 17,99,408 is 1 .
LCM of Denominators means LCM of 83,64,85 as per the given fractions.
LCM of 83,64,85 is 451520 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 17,99,408
∴ So GCF of numbers is 1 because of no common factors present between them.

Greatest Common Factor
We found the factors 17,99,408 . The biggest common factor number is the GCF number.
So the greatest common factor 17,99,408 is 1.
Lets's calculate LCM of 83,64,85
Given numbers has no common factors except 1. So, there LCM is their product i.e 451520
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/451520
Therefore, the GCF of Fractions 17/83,99/64,408/85 is 1/451520
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 83,64,85 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(83,64,85) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(83,64,85) x common factors =1 x 1 = 1
LCM(83,64,85) = ( 83 × 64 × 85 ) / 1
LCM(83,64,85) = 451520 / 1
LCM(83,64,85) = 451520
Here are some samples of GCF of Fractions calculations.
