Lets's calculate LCM of 462,978
2 | 462, 978 |
3 | 231, 489 |
77, 163 |
∴ So the LCM of the given numbers is 2 x 3 x 77 x 163 = 75306
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/75306
Therefore, the GCF of Fractions 455/462,143/978 is 13/75306
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 462,978 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(462,978) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(462,978) x common factors =6 x 1 = 6
LCM(462,978) = ( 462 × 978 ) / 6
LCM(462,978) = 451836 / 6
LCM(462,978) = 75306
