We found the factors 84,55,809 . The biggest common factor number is the GCF number.
So the greatest common factor 84,55,809 is 1.
Lets's calculate LCM of 498,390,843
2 | 498, 390, 843 |
3 | 249, 195, 843 |
83, 65, 281 |
∴ So the LCM of the given numbers is 2 x 3 x 83 x 65 x 281 = 9095970
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9095970
Therefore, the GCF of Fractions 84/498,55/390,809/843 is 1/9095970
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 498,390,843 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(498,390,843) = 3
common factors(in case of two or more numbers have common factors) = 6
GCF(498,390,843) x common factors =3 x 6 = 18
LCM(498,390,843) = ( 498 × 390 × 843 ) / 18
LCM(498,390,843) = 163727460 / 18
LCM(498,390,843) = 9095970
