Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 275/136,7950/139
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 275,7950
Greatest Common Factor of Numerators i.e. GCF of 275,7950 is 25 .
LCM of Denominators means LCM of 136,139 as per the given fractions.
LCM of 136,139 is 18904 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 275,7950
5 | 275, 7950 |
5 | 55, 1590 |
11, 318 |
∴ So the GCF of the given numbers is 5 x 5 = 25

Greatest Common Factor
We found the factors 275,7950 . The biggest common factor number is the GCF number.
So the greatest common factor 275,7950 is 25.
Lets's calculate LCM of 136,139
Given numbers has no common factors except 1. So, there LCM is their product i.e 18904
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 25/18904
Therefore, the GCF of Fractions 275/136,7950/139 is 25/18904
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 136,139 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(136,139) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(136,139) x common factors =1 x 1 = 1
LCM(136,139) = ( 136 × 139 ) / 1
LCM(136,139) = 18904 / 1
LCM(136,139) = 18904
Here are some samples of GCF of Fractions calculations.
