Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 23/11,74/87,538/91
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 23,74,538
Greatest Common Factor of Numerators i.e. GCF of 23,74,538 is 1 .
LCM of Denominators means LCM of 11,87,91 as per the given fractions.
LCM of 11,87,91 is 87087 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 23,74,538
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 23
List of positive integer factors of 23 that divides 23 without a remainder.
1,23
Factors of 74
List of positive integer factors of 74 that divides 74 without a remainder.
1,2,37,74
Factors of 538
List of positive integer factors of 538 that divides 538 without a remainder.
1,2,269,538
Greatest Common Factor
We found the factors 23,74,538 . The biggest common factor number is the GCF number.
So the greatest common factor 23,74,538 is 1.
Lets's calculate LCM of 11,87,91
Given numbers has no common factors except 1. So, there LCM is their product i.e 87087
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/87087
Therefore, the GCF of Fractions 23/11,74/87,538/91 is 1/87087
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 11,87,91 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(11,87,91) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(11,87,91) x common factors =1 x 1 = 1
LCM(11,87,91) = ( 11 × 87 × 91 ) / 1
LCM(11,87,91) = 87087 / 1
LCM(11,87,91) = 87087
Here are some samples of GCF of Fractions calculations.
