So the greatest common factor 992,891 is 1.
Lets's calculate LCM of 810,978
2 | 810, 978 |
3 | 405, 489 |
135, 163 |
∴ So the LCM of the given numbers is 2 x 3 x 135 x 163 = 132030
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/132030
Therefore, the GCF of Fractions 992/810,891/978 is 1/132030
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 810,978 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(810,978) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(810,978) x common factors =6 x 1 = 6
LCM(810,978) = ( 810 × 978 ) / 6
LCM(810,978) = 792180 / 6
LCM(810,978) = 132030
