So the greatest common factor 30,89,434 is 1.
Lets's calculate LCM of 849,690,804
2 | 849, 690, 804 |
3 | 849, 345, 402 |
283, 115, 134 |
∴ So the LCM of the given numbers is 2 x 3 x 283 x 115 x 134 = 26166180
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/26166180
Therefore, the GCF of Fractions 30/849,89/690,434/804 is 1/26166180
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 849,690,804 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(849,690,804) = 3
common factors(in case of two or more numbers have common factors) = 6
GCF(849,690,804) x common factors =3 x 6 = 18
LCM(849,690,804) = ( 849 × 690 × 804 ) / 18
LCM(849,690,804) = 470991240 / 18
LCM(849,690,804) = 26166180
