Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 868/15,426/696
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 868,426
Greatest Common Factor of Numerators i.e. GCF of 868,426 is 2 .
LCM of Denominators means LCM of 15,696 as per the given fractions.
LCM of 15,696 is 3480 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 868,426
2 | 868, 426 |
434, 213 |
∴ So the GCF of the given numbers is 2 = 2

Factors of 426
List of positive integer factors of 426 that divides 426 without a remainder.
1,2,3,6,71,142,213,426
Greatest Common Factor
We found the factors 868,426 . The biggest common factor number is the GCF number.
So the greatest common factor 868,426 is 2.
Lets's calculate LCM of 15,696
3 | 15, 696 |
5, 232 |
∴ So the LCM of the given numbers is 3 x 5 x 232 = 3480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/3480
Therefore, the GCF of Fractions 868/15,426/696 is 2/3480
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 15,696 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,696) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(15,696) x common factors =3 x 1 = 3
LCM(15,696) = ( 15 × 696 ) / 3
LCM(15,696) = 10440 / 3
LCM(15,696) = 3480
