Lets's calculate LCM of 678,310,981
2 | 678, 310, 981 |
3 | 339, 155, 981 |
113, 155, 327 |
∴ So the LCM of the given numbers is 2 x 3 x 113 x 155 x 327 = 34364430
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/34364430
Therefore, the GCF of Fractions 200/678,512/310,908/981 is 4/34364430
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 678,310,981 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(678,310,981) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(678,310,981) x common factors =1 x 6 = 6
LCM(678,310,981) = ( 678 × 310 × 981 ) / 6
LCM(678,310,981) = 206186580 / 6
LCM(678,310,981) = 34364430
