Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 205/18,540/869
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 205,540
Greatest Common Factor of Numerators i.e. GCF of 205,540 is 5 .
LCM of Denominators means LCM of 18,869 as per the given fractions.
LCM of 18,869 is 15642 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 205,540
5 | 205, 540 |
41, 108 |
∴ So the GCF of the given numbers is 5 = 5

Greatest Common Factor
We found the factors 205,540 . The biggest common factor number is the GCF number.
So the greatest common factor 205,540 is 5.
Lets's calculate LCM of 18,869
Given numbers has no common factors except 1. So, there LCM is their product i.e 15642
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/15642
Therefore, the GCF of Fractions 205/18,540/869 is 5/15642
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 18,869 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(18,869) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(18,869) x common factors =1 x 1 = 1
LCM(18,869) = ( 18 × 869 ) / 1
LCM(18,869) = 15642 / 1
LCM(18,869) = 15642
