Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 490/11,399/9753
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 490,399
Greatest Common Factor of Numerators i.e. GCF of 490,399 is 7 .
LCM of Denominators means LCM of 11,9753 as per the given fractions.
LCM of 11,9753 is 107283 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 490,399
7 | 490, 399 |
70, 57 |
∴ So the GCF of the given numbers is 7 = 7

Factors of 399
List of positive integer factors of 399 that divides 399 without a remainder.
1,3,7,19,21,57,133,399
Greatest Common Factor
We found the factors 490,399 . The biggest common factor number is the GCF number.
So the greatest common factor 490,399 is 7.
Lets's calculate LCM of 11,9753
Given numbers has no common factors except 1. So, there LCM is their product i.e 107283
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/107283
Therefore, the GCF of Fractions 490/11,399/9753 is 7/107283
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 11,9753 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(11,9753) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(11,9753) x common factors =1 x 1 = 1
LCM(11,9753) = ( 11 × 9753 ) / 1
LCM(11,9753) = 107283 / 1
LCM(11,9753) = 107283
Here are some samples of GCF of Fractions calculations.
