We found the factors 490,184 . The biggest common factor number is the GCF number.
So the greatest common factor 490,184 is 2.
Lets's calculate LCM of 81,1797
3 | 81, 1797 |
27, 599 |
∴ So the LCM of the given numbers is 3 x 27 x 599 = 48519
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/48519
Therefore, the GCF of Fractions 490/81,184/1797 is 2/48519
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 81,1797 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,1797) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(81,1797) x common factors =3 x 1 = 3
LCM(81,1797) = ( 81 × 1797 ) / 3
LCM(81,1797) = 145557 / 3
LCM(81,1797) = 48519
