Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 27/59,36/81,231/18
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 27,36,231
Greatest Common Factor of Numerators i.e. GCF of 27,36,231 is 3 .
LCM of Denominators means LCM of 59,81,18 as per the given fractions.
LCM of 59,81,18 is 9558 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 27,36,231
3 | 27, 36, 231 |
9, 12, 77 |
∴ So the GCF of the given numbers is 3 = 3

List of positive integer factors of 36 that divides 36 without a remainder.
1,2,3,4,6,9,12,18,36
Factors of 231
List of positive integer factors of 231 that divides 231 without a remainder.
1,3,7,11,21,33,77,231
Greatest Common Factor
We found the factors 27,36,231 . The biggest common factor number is the GCF number.
So the greatest common factor 27,36,231 is 3.
Lets's calculate LCM of 59,81,18
3 | 59, 81, 18 |
3 | 59, 27, 6 |
59, 9, 2 |
∴ So the LCM of the given numbers is 3 x 3 x 59 x 9 x 2 = 9558
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/9558
Therefore, the GCF of Fractions 27/59,36/81,231/18 is 3/9558
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 59,81,18 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(59,81,18) = 1
common factors(in case of two or more numbers have common factors) = 9
GCF(59,81,18) x common factors =1 x 9 = 9
LCM(59,81,18) = ( 59 × 81 × 18 ) / 9
LCM(59,81,18) = 86022 / 9
LCM(59,81,18) = 9558
