Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 861/92,1908/449
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 861,1908
Greatest Common Factor of Numerators i.e. GCF of 861,1908 is 3 .
LCM of Denominators means LCM of 92,449 as per the given fractions.
LCM of 92,449 is 41308 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 861,1908
3 | 861, 1908 |
287, 636 |
∴ So the GCF of the given numbers is 3 = 3

Factors of 1908
List of positive integer factors of 1908 that divides 1908 without a remainder.
1,2,3,4,6,9,12,18,36,53,106,159,212,318,477,636,954,1908
Greatest Common Factor
We found the factors 861,1908 . The biggest common factor number is the GCF number.
So the greatest common factor 861,1908 is 3.
Lets's calculate LCM of 92,449
Given numbers has no common factors except 1. So, there LCM is their product i.e 41308
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/41308
Therefore, the GCF of Fractions 861/92,1908/449 is 3/41308
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 92,449 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(92,449) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(92,449) x common factors =1 x 1 = 1
LCM(92,449) = ( 92 × 449 ) / 1
LCM(92,449) = 41308 / 1
LCM(92,449) = 41308
