Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 194/772,3986/839
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 194,3986
Greatest Common Factor of Numerators i.e. GCF of 194,3986 is 2 .
LCM of Denominators means LCM of 772,839 as per the given fractions.
LCM of 772,839 is 647708 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 194,3986
2 | 194, 3986 |
97, 1993 |
∴ So the GCF of the given numbers is 2 = 2

Factors of 3986
List of positive integer factors of 3986 that divides 3986 without a remainder.
1,2,1993,3986
Greatest Common Factor
We found the factors 194,3986 . The biggest common factor number is the GCF number.
So the greatest common factor 194,3986 is 2.
Lets's calculate LCM of 772,839
Given numbers has no common factors except 1. So, there LCM is their product i.e 647708
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/647708
Therefore, the GCF of Fractions 194/772,3986/839 is 2/647708
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 772,839 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(772,839) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(772,839) x common factors =1 x 1 = 1
LCM(772,839) = ( 772 × 839 ) / 1
LCM(772,839) = 647708 / 1
LCM(772,839) = 647708
Here are some samples of GCF of Fractions calculations.
