Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 30/43,87/53,393/751
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 30,87,393
Greatest Common Factor of Numerators i.e. GCF of 30,87,393 is 3 .
LCM of Denominators means LCM of 43,53,751 as per the given fractions.
LCM of 43,53,751 is 1711529 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 30,87,393
3 | 30, 87, 393 |
10, 29, 131 |
∴ So the GCF of the given numbers is 3 = 3
Factors of 30
List of positive integer factors of 30 that divides 30 without a remainder.
1,2,3,5,6,10,15,30

Greatest Common Factor
We found the factors 30,87,393 . The biggest common factor number is the GCF number.
So the greatest common factor 30,87,393 is 3.
Lets's calculate LCM of 43,53,751
Given numbers has no common factors except 1. So, there LCM is their product i.e 1711529
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/1711529
Therefore, the GCF of Fractions 30/43,87/53,393/751 is 3/1711529
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 43,53,751 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(43,53,751) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(43,53,751) x common factors =1 x 1 = 1
LCM(43,53,751) = ( 43 × 53 × 751 ) / 1
LCM(43,53,751) = 1711529 / 1
LCM(43,53,751) = 1711529
Here are some samples of GCF of Fractions calculations.
