Lets's calculate LCM of 330,823,198
2 | 330, 823, 198 |
3 | 165, 823, 99 |
11 | 55, 823, 33 |
5, 823, 3 |
∴ So the LCM of the given numbers is 2 x 3 x 11 x 5 x 823 x 3 = 814770
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/814770
Therefore, the GCF of Fractions 54/330,45/823,171/198 is 9/814770
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 330,823,198 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(330,823,198) = 1
common factors(in case of two or more numbers have common factors) = 66
GCF(330,823,198) x common factors =1 x 66 = 66
LCM(330,823,198) = ( 330 × 823 × 198 ) / 66
LCM(330,823,198) = 53774820 / 66
LCM(330,823,198) = 814770
