Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 86/23,13/69,311/931
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 86,13,311
Greatest Common Factor of Numerators i.e. GCF of 86,13,311 is 1 .
LCM of Denominators means LCM of 23,69,931 as per the given fractions.
LCM of 23,69,931 is 64239 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 86,13,311
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 86
List of positive integer factors of 86 that divides 86 without a remainder.
1,2,43,86

1,13
Factors of 311
List of positive integer factors of 311 that divides 311 without a remainder.
1,311
Greatest Common Factor
We found the factors 86,13,311 . The biggest common factor number is the GCF number.
So the greatest common factor 86,13,311 is 1.
Lets's calculate LCM of 23,69,931
23 | 23, 69, 931 |
1, 3, 931 |
∴ So the LCM of the given numbers is 23 x 1 x 3 x 931 = 64239
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/64239
Therefore, the GCF of Fractions 86/23,13/69,311/931 is 1/64239
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 23,69,931 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(23,69,931) = 1
common factors(in case of two or more numbers have common factors) = 23
GCF(23,69,931) x common factors =1 x 23 = 23
LCM(23,69,931) = ( 23 × 69 × 931 ) / 23
LCM(23,69,931) = 1477497 / 23
LCM(23,69,931) = 64239
