Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 305/198,805/505
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 305,805
Greatest Common Factor of Numerators i.e. GCF of 305,805 is 5 .
LCM of Denominators means LCM of 198,505 as per the given fractions.
LCM of 198,505 is 99990 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 305,805
5 | 305, 805 |
61, 161 |
∴ So the GCF of the given numbers is 5 = 5

1,5,61,305
Factors of 805
List of positive integer factors of 805 that divides 805 without a remainder.
1,5,7,23,35,115,161,805
Greatest Common Factor
We found the factors 305,805 . The biggest common factor number is the GCF number.
So the greatest common factor 305,805 is 5.
Lets's calculate LCM of 198,505
Given numbers has no common factors except 1. So, there LCM is their product i.e 99990
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/99990
Therefore, the GCF of Fractions 305/198,805/505 is 5/99990
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 198,505 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(198,505) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(198,505) x common factors =1 x 1 = 1
LCM(198,505) = ( 198 × 505 ) / 1
LCM(198,505) = 99990 / 1
LCM(198,505) = 99990
