Lets's calculate LCM of 984,811,904
2 | 984, 811, 904 |
2 | 492, 811, 452 |
2 | 246, 811, 226 |
123, 811, 113 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 123 x 811 x 113 = 90176712
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/90176712
Therefore, the GCF of Fractions 492/984,424/811,420/904 is 4/90176712
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 984,811,904 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(984,811,904) = 1
common factors(in case of two or more numbers have common factors) = 8
GCF(984,811,904) x common factors =1 x 8 = 8
LCM(984,811,904) = ( 984 × 811 × 904 ) / 8
LCM(984,811,904) = 721413696 / 8
LCM(984,811,904) = 90176712
