So the greatest common factor 143,840 is 1.
Lets's calculate LCM of 954,450
2 | 954, 450 |
3 | 477, 225 |
3 | 159, 75 |
53, 25 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 53 x 25 = 23850
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/23850
Therefore, the GCF of Fractions 143/954,840/450 is 1/23850
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 954,450 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(954,450) = 18
common factors(in case of two or more numbers have common factors) = 1
GCF(954,450) x common factors =18 x 1 = 18
LCM(954,450) = ( 954 × 450 ) / 18
LCM(954,450) = 429300 / 18
LCM(954,450) = 23850
