So the greatest common factor 687,4122 is 687.
Lets's calculate LCM of 459,315
3 | 459, 315 |
3 | 153, 105 |
51, 35 |
∴ So the LCM of the given numbers is 3 x 3 x 51 x 35 = 16065
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 687/16065
Therefore, the GCF of Fractions 687/459,4122/315 is 687/16065
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 459,315 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(459,315) = 9
common factors(in case of two or more numbers have common factors) = 1
GCF(459,315) x common factors =9 x 1 = 9
LCM(459,315) = ( 459 × 315 ) / 9
LCM(459,315) = 144585 / 9
LCM(459,315) = 16065
