Lets's calculate LCM of 784,571,862
2 | 784, 571, 862 |
392, 571, 431 |
∴ So the LCM of the given numbers is 2 x 392 x 571 x 431 = 192943184
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/192943184
Therefore, the GCF of Fractions 90/784,949/571,430/862 is 1/192943184
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 784,571,862 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(784,571,862) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(784,571,862) x common factors =1 x 2 = 2
LCM(784,571,862) = ( 784 × 571 × 862 ) / 2
LCM(784,571,862) = 385886368 / 2
LCM(784,571,862) = 192943184
