Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 2185/22,3849/979
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 2185,3849
Greatest Common Factor of Numerators i.e. GCF of 2185,3849 is 1 .
LCM of Denominators means LCM of 22,979 as per the given fractions.
LCM of 22,979 is 1958 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 2185,3849
∴ So GCF of numbers is 1 because of no common factors present between them.

Factors of 3849
List of positive integer factors of 3849 that divides 3849 without a remainder.
1,3,1283,3849
Greatest Common Factor
We found the factors 2185,3849 . The biggest common factor number is the GCF number.
So the greatest common factor 2185,3849 is 1.
Lets's calculate LCM of 22,979
11 | 22, 979 |
2, 89 |
∴ So the LCM of the given numbers is 11 x 2 x 89 = 1958
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1958
Therefore, the GCF of Fractions 2185/22,3849/979 is 1/1958
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 22,979 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(22,979) = 11
common factors(in case of two or more numbers have common factors) = 1
GCF(22,979) x common factors =11 x 1 = 11
LCM(22,979) = ( 22 × 979 ) / 11
LCM(22,979) = 21538 / 11
LCM(22,979) = 1958
