Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 838/81,2057/342
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 838,2057
Greatest Common Factor of Numerators i.e. GCF of 838,2057 is 1 .
LCM of Denominators means LCM of 81,342 as per the given fractions.
LCM of 81,342 is 3078 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 838,2057
∴ So GCF of numbers is 1 because of no common factors present between them.

1,2,419,838
Factors of 2057
List of positive integer factors of 2057 that divides 2057 without a remainder.
1,11,17,121,187,2057
Greatest Common Factor
We found the factors 838,2057 . The biggest common factor number is the GCF number.
So the greatest common factor 838,2057 is 1.
Lets's calculate LCM of 81,342
3 | 81, 342 |
3 | 27, 114 |
9, 38 |
∴ So the LCM of the given numbers is 3 x 3 x 9 x 38 = 3078
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3078
Therefore, the GCF of Fractions 838/81,2057/342 is 1/3078
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 81,342 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,342) = 9
common factors(in case of two or more numbers have common factors) = 1
GCF(81,342) x common factors =9 x 1 = 9
LCM(81,342) = ( 81 × 342 ) / 9
LCM(81,342) = 27702 / 9
LCM(81,342) = 3078
