Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 619/45,399/2001
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 619,399
Greatest Common Factor of Numerators i.e. GCF of 619,399 is 1 .
LCM of Denominators means LCM of 45,2001 as per the given fractions.
LCM of 45,2001 is 30015 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 619,399
∴ So GCF of numbers is 1 because of no common factors present between them.

1,619
Factors of 399
List of positive integer factors of 399 that divides 399 without a remainder.
1,3,7,19,21,57,133,399
Greatest Common Factor
We found the factors 619,399 . The biggest common factor number is the GCF number.
So the greatest common factor 619,399 is 1.
Lets's calculate LCM of 45,2001
3 | 45, 2001 |
15, 667 |
∴ So the LCM of the given numbers is 3 x 15 x 667 = 30015
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/30015
Therefore, the GCF of Fractions 619/45,399/2001 is 1/30015
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 45,2001 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(45,2001) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(45,2001) x common factors =3 x 1 = 3
LCM(45,2001) = ( 45 × 2001 ) / 3
LCM(45,2001) = 90045 / 3
LCM(45,2001) = 30015
