Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 686/71,946/1389
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 686,946
Greatest Common Factor of Numerators i.e. GCF of 686,946 is 2 .
LCM of Denominators means LCM of 71,1389 as per the given fractions.
LCM of 71,1389 is 98619 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 686,946
2 | 686, 946 |
343, 473 |
∴ So the GCF of the given numbers is 2 = 2

Factors of 946
List of positive integer factors of 946 that divides 946 without a remainder.
1,2,11,22,43,86,473,946
Greatest Common Factor
We found the factors 686,946 . The biggest common factor number is the GCF number.
So the greatest common factor 686,946 is 2.
Lets's calculate LCM of 71,1389
Given numbers has no common factors except 1. So, there LCM is their product i.e 98619
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/98619
Therefore, the GCF of Fractions 686/71,946/1389 is 2/98619
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 71,1389 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(71,1389) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(71,1389) x common factors =1 x 1 = 1
LCM(71,1389) = ( 71 × 1389 ) / 1
LCM(71,1389) = 98619 / 1
LCM(71,1389) = 98619
