Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 83/85,82/27,617/921
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 83,82,617
Greatest Common Factor of Numerators i.e. GCF of 83,82,617 is 1 .
LCM of Denominators means LCM of 85,27,921 as per the given fractions.
LCM of 85,27,921 is 704565 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 83,82,617
∴ So GCF of numbers is 1 because of no common factors present between them.

1,2,41,82
Factors of 617
List of positive integer factors of 617 that divides 617 without a remainder.
1,617
Greatest Common Factor
We found the factors 83,82,617 . The biggest common factor number is the GCF number.
So the greatest common factor 83,82,617 is 1.
Lets's calculate LCM of 85,27,921
3 | 85, 27, 921 |
85, 9, 307 |
∴ So the LCM of the given numbers is 3 x 85 x 9 x 307 = 704565
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/704565
Therefore, the GCF of Fractions 83/85,82/27,617/921 is 1/704565
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 85,27,921 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,27,921) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(85,27,921) x common factors =1 x 3 = 3
LCM(85,27,921) = ( 85 × 27 × 921 ) / 3
LCM(85,27,921) = 2113695 / 3
LCM(85,27,921) = 704565
