So the greatest common factor 19,866,990 is 1.
Lets's calculate LCM of 142,474,437
2 | 142, 474, 437 |
71, 237, 437 |
∴ So the LCM of the given numbers is 2 x 71 x 237 x 437 = 14706798
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/14706798
Therefore, the GCF of Fractions 19/142,866/474,990/437 is 1/14706798
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 142,474,437 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(142,474,437) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(142,474,437) x common factors =1 x 2 = 2
LCM(142,474,437) = ( 142 × 474 × 437 ) / 2
LCM(142,474,437) = 29413596 / 2
LCM(142,474,437) = 14706798
