Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 831/69,691/789
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 831,691
Greatest Common Factor of Numerators i.e. GCF of 831,691 is 1 .
LCM of Denominators means LCM of 69,789 as per the given fractions.
LCM of 69,789 is 18147 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 831,691
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 831

1,3,277,831
Factors of 691
List of positive integer factors of 691 that divides 691 without a remainder.
1,691
Greatest Common Factor
We found the factors 831,691 . The biggest common factor number is the GCF number.
So the greatest common factor 831,691 is 1.
Lets's calculate LCM of 69,789
3 | 69, 789 |
23, 263 |
∴ So the LCM of the given numbers is 3 x 23 x 263 = 18147
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/18147
Therefore, the GCF of Fractions 831/69,691/789 is 1/18147
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 69,789 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(69,789) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(69,789) x common factors =3 x 1 = 3
LCM(69,789) = ( 69 × 789 ) / 3
LCM(69,789) = 54441 / 3
LCM(69,789) = 18147
