Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 11/73,30/11,91/12
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 11,30,91
Greatest Common Factor of Numerators i.e. GCF of 11,30,91 is 1 .
LCM of Denominators means LCM of 73,11,12 as per the given fractions.
LCM of 73,11,12 is 9636 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 11,30,91
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 11
List of positive integer factors of 11 that divides 11 without a remainder.
1,11
Factors of 30
List of positive integer factors of 30 that divides 30 without a remainder.
1,2,3,5,6,10,15,30
Factors of 91
List of positive integer factors of 91 that divides 91 without a remainder.
1,7,13,91
Greatest Common Factor
We found the factors 11,30,91 . The biggest common factor number is the GCF number.
So the greatest common factor 11,30,91 is 1.
Lets's calculate LCM of 73,11,12
Given numbers has no common factors except 1. So, there LCM is their product i.e 9636
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9636
Therefore, the GCF of Fractions 11/73,30/11,91/12 is 1/9636
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 73,11,12 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(73,11,12) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(73,11,12) x common factors =1 x 1 = 1
LCM(73,11,12) = ( 73 × 11 × 12 ) / 1
LCM(73,11,12) = 9636 / 1
LCM(73,11,12) = 9636
Here are some samples of GCF of Fractions calculations.
