Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 58/32,18/27,40/60,12/54
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 58,18,40,12
Greatest Common Factor of Numerators i.e. GCF of 58,18,40,12 is 2 .
LCM of Denominators means LCM of 32,27,60,54 as per the given fractions.
LCM of 32,27,60,54 is 4320 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 58,18,40,12
2 | 58, 18, 40, 12 |
29, 9, 20, 6 |
∴ So the GCF of the given numbers is 2 = 2

Greatest Common Factor
We found the factors 58,18,40,12 . The biggest common factor number is the GCF number.
So the greatest common factor 58,18,40,12 is 2.
Lets's calculate LCM of 32,27,60,54
2 | 32, 27, 60, 54 |
2 | 16, 27, 30, 27 |
3 | 8, 27, 15, 27 |
3 | 8, 9, 5, 9 |
3 | 8, 3, 5, 3 |
8, 1, 5, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 3 x 8 x 1 x 5 x 1 = 4320
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/4320
Therefore, the GCF of Fractions 58/32,18/27,40/60,12/54 is 2/4320
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 32,27,60,54 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(32,27,60,54) = 1
common factors(in case of two or more numbers have common factors) = 648
GCF(32,27,60,54) x common factors =1 x 648 = 648
LCM(32,27,60,54) = ( 32 × 27 × 60 × 54 ) / 648
LCM(32,27,60,54) = 2799360 / 648
LCM(32,27,60,54) = 4320
