Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 27/22,19/80,672/880
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 27,19,672
Greatest Common Factor of Numerators i.e. GCF of 27,19,672 is 1 .
LCM of Denominators means LCM of 22,80,880 as per the given fractions.
LCM of 22,80,880 is 880 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 27,19,672
∴ So GCF of numbers is 1 because of no common factors present between them.

Greatest Common Factor
We found the factors 27,19,672 . The biggest common factor number is the GCF number.
So the greatest common factor 27,19,672 is 1.
Lets's calculate LCM of 22,80,880
2 | 22, 80, 880 |
2 | 11, 40, 440 |
2 | 11, 20, 220 |
2 | 11, 10, 110 |
5 | 11, 5, 55 |
11 | 11, 1, 11 |
1, 1, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 5 x 11 x 1 x 1 x 1 = 880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/880
Therefore, the GCF of Fractions 27/22,19/80,672/880 is 1/880
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 22,80,880 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(22,80,880) = 2
common factors(in case of two or more numbers have common factors) = 880
GCF(22,80,880) x common factors =2 x 880 = 1760
LCM(22,80,880) = ( 22 × 80 × 880 ) / 1760
LCM(22,80,880) = 1548800 / 1760
LCM(22,80,880) = 880
