Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 142/99,138/4227
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 142,138
Greatest Common Factor of Numerators i.e. GCF of 142,138 is 2 .
LCM of Denominators means LCM of 99,4227 as per the given fractions.
LCM of 99,4227 is 139491 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 142,138
2 | 142, 138 |
71, 69 |
∴ So the GCF of the given numbers is 2 = 2

1,2,3,6,23,46,69,138
Greatest Common Factor
We found the factors 142,138 . The biggest common factor number is the GCF number.
So the greatest common factor 142,138 is 2.
Lets's calculate LCM of 99,4227
3 | 99, 4227 |
33, 1409 |
∴ So the LCM of the given numbers is 3 x 33 x 1409 = 139491
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/139491
Therefore, the GCF of Fractions 142/99,138/4227 is 2/139491
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 99,4227 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(99,4227) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(99,4227) x common factors =3 x 1 = 3
LCM(99,4227) = ( 99 × 4227 ) / 3
LCM(99,4227) = 418473 / 3
LCM(99,4227) = 139491
