Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 821/202,2081/840
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 821,2081
Greatest Common Factor of Numerators i.e. GCF of 821,2081 is 1 .
LCM of Denominators means LCM of 202,840 as per the given fractions.
LCM of 202,840 is 84840 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 821,2081
∴ So GCF of numbers is 1 because of no common factors present between them.

1,821
Factors of 2081
List of positive integer factors of 2081 that divides 2081 without a remainder.
1,2081
Greatest Common Factor
We found the factors 821,2081 . The biggest common factor number is the GCF number.
So the greatest common factor 821,2081 is 1.
Lets's calculate LCM of 202,840
2 | 202, 840 |
101, 420 |
∴ So the LCM of the given numbers is 2 x 101 x 420 = 84840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/84840
Therefore, the GCF of Fractions 821/202,2081/840 is 1/84840
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 202,840 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(202,840) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(202,840) x common factors =2 x 1 = 2
LCM(202,840) = ( 202 × 840 ) / 2
LCM(202,840) = 169680 / 2
LCM(202,840) = 84840
