Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 18/116,990/987
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 18,990
Greatest Common Factor of Numerators i.e. GCF of 18,990 is 18 .
LCM of Denominators means LCM of 116,987 as per the given fractions.
LCM of 116,987 is 114492 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 18,990
2 | 18, 990 |
3 | 9, 495 |
3 | 3, 165 |
1, 55 |
∴ So the GCF of the given numbers is 2 x 3 x 3 = 18

1,2,3,6,9,18
Factors of 990
List of positive integer factors of 990 that divides 990 without a remainder.
1,2,3,5,6,9,10,11,15,18,22,30,33,45,55,66,90,99,110,165,198,330,495,990
Greatest Common Factor
We found the factors 18,990 . The biggest common factor number is the GCF number.
So the greatest common factor 18,990 is 18.
Lets's calculate LCM of 116,987
Given numbers has no common factors except 1. So, there LCM is their product i.e 114492
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 18/114492
Therefore, the GCF of Fractions 18/116,990/987 is 18/114492
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 116,987 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(116,987) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(116,987) x common factors =1 x 1 = 1
LCM(116,987) = ( 116 × 987 ) / 1
LCM(116,987) = 114492 / 1
LCM(116,987) = 114492
Here are some samples of GCF of Fractions calculations.
