Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 7/96,4/39,79/57,43/864
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 7,4,79,43
Greatest Common Factor of Numerators i.e. GCF of 7,4,79,43 is 1 .
LCM of Denominators means LCM of 96,39,57,864 as per the given fractions.
LCM of 96,39,57,864 is 213408 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 7,4,79,43
∴ So GCF of numbers is 1 because of no common factors present between them.

Greatest Common Factor
We found the factors 7,4,79,43 . The biggest common factor number is the GCF number.
So the greatest common factor 7,4,79,43 is 1.
Lets's calculate LCM of 96,39,57,864
2 | 96, 39, 57, 864 |
2 | 48, 39, 57, 432 |
2 | 24, 39, 57, 216 |
2 | 12, 39, 57, 108 |
2 | 6, 39, 57, 54 |
3 | 3, 39, 57, 27 |
1, 13, 19, 9 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 2 x 3 x 1 x 13 x 19 x 9 = 213408
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/213408
Therefore, the GCF of Fractions 7/96,4/39,79/57,43/864 is 1/213408
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 96,39,57,864 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(96,39,57,864) = 3
common factors(in case of two or more numbers have common factors) = 288
GCF(96,39,57,864) x common factors =3 x 288 = 864
LCM(96,39,57,864) = ( 96 × 39 × 57 × 864 ) / 864
LCM(96,39,57,864) = 184384512 / 864
LCM(96,39,57,864) = 213408
