Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 998/18,590/2980
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 998,590
Greatest Common Factor of Numerators i.e. GCF of 998,590 is 2 .
LCM of Denominators means LCM of 18,2980 as per the given fractions.
LCM of 18,2980 is 26820 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 998,590
2 | 998, 590 |
499, 295 |
∴ So the GCF of the given numbers is 2 = 2

1,2,5,10,59,118,295,590
Greatest Common Factor
We found the factors 998,590 . The biggest common factor number is the GCF number.
So the greatest common factor 998,590 is 2.
Lets's calculate LCM of 18,2980
2 | 18, 2980 |
9, 1490 |
∴ So the LCM of the given numbers is 2 x 9 x 1490 = 26820
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/26820
Therefore, the GCF of Fractions 998/18,590/2980 is 2/26820
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 18,2980 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(18,2980) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(18,2980) x common factors =2 x 1 = 2
LCM(18,2980) = ( 18 × 2980 ) / 2
LCM(18,2980) = 53640 / 2
LCM(18,2980) = 26820
