So the greatest common factor 68,654,518 is 2.
Lets's calculate LCM of 159,378,408
2 | 159, 378, 408 |
3 | 159, 189, 204 |
53, 63, 68 |
∴ So the LCM of the given numbers is 2 x 3 x 53 x 63 x 68 = 1362312
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/1362312
Therefore, the GCF of Fractions 68/159,654/378,518/408 is 2/1362312
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 159,378,408 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(159,378,408) = 3
common factors(in case of two or more numbers have common factors) = 6
GCF(159,378,408) x common factors =3 x 6 = 18
LCM(159,378,408) = ( 159 × 378 × 408 ) / 18
LCM(159,378,408) = 24521616 / 18
LCM(159,378,408) = 1362312
