Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 685/137,7305/965
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 685,7305
Greatest Common Factor of Numerators i.e. GCF of 685,7305 is 5 .
LCM of Denominators means LCM of 137,965 as per the given fractions.
LCM of 137,965 is 132205 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 685,7305
5 | 685, 7305 |
137, 1461 |
∴ So the GCF of the given numbers is 5 = 5

1,5,137,685
Factors of 7305
List of positive integer factors of 7305 that divides 7305 without a remainder.
1,3,5,15,487,1461,2435,7305
Greatest Common Factor
We found the factors 685,7305 . The biggest common factor number is the GCF number.
So the greatest common factor 685,7305 is 5.
Lets's calculate LCM of 137,965
Given numbers has no common factors except 1. So, there LCM is their product i.e 132205
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/132205
Therefore, the GCF of Fractions 685/137,7305/965 is 5/132205
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 137,965 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(137,965) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(137,965) x common factors =1 x 1 = 1
LCM(137,965) = ( 137 × 965 ) / 1
LCM(137,965) = 132205 / 1
LCM(137,965) = 132205
Here are some samples of GCF of Fractions calculations.
