Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 405/49,655/6896
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 405,655
Greatest Common Factor of Numerators i.e. GCF of 405,655 is 5 .
LCM of Denominators means LCM of 49,6896 as per the given fractions.
LCM of 49,6896 is 337904 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 405,655
5 | 405, 655 |
81, 131 |
∴ So the GCF of the given numbers is 5 = 5

1,3,5,9,15,27,45,81,135,405
Factors of 655
List of positive integer factors of 655 that divides 655 without a remainder.
1,5,131,655
Greatest Common Factor
We found the factors 405,655 . The biggest common factor number is the GCF number.
So the greatest common factor 405,655 is 5.
Lets's calculate LCM of 49,6896
Given numbers has no common factors except 1. So, there LCM is their product i.e 337904
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/337904
Therefore, the GCF of Fractions 405/49,655/6896 is 5/337904
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 49,6896 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(49,6896) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(49,6896) x common factors =1 x 1 = 1
LCM(49,6896) = ( 49 × 6896 ) / 1
LCM(49,6896) = 337904 / 1
LCM(49,6896) = 337904
Here are some samples of GCF of Fractions calculations.
