Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 53/81,74/26,688/59
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 53,74,688
Greatest Common Factor of Numerators i.e. GCF of 53,74,688 is 1 .
LCM of Denominators means LCM of 81,26,59 as per the given fractions.
LCM of 81,26,59 is 124254 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 53,74,688
∴ So GCF of numbers is 1 because of no common factors present between them.

1,2,4,8,16,43,86,172,344,688
Greatest Common Factor
We found the factors 53,74,688 . The biggest common factor number is the GCF number.
So the greatest common factor 53,74,688 is 1.
Lets's calculate LCM of 81,26,59
Given numbers has no common factors except 1. So, there LCM is their product i.e 124254
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/124254
Therefore, the GCF of Fractions 53/81,74/26,688/59 is 1/124254
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 81,26,59 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,26,59) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(81,26,59) x common factors =1 x 1 = 1
LCM(81,26,59) = ( 81 × 26 × 59 ) / 1
LCM(81,26,59) = 124254 / 1
LCM(81,26,59) = 124254
Here are some samples of GCF of Fractions calculations.
