- Least Common Multiple of 243, 810 by common division method
- Least Common Multiple of 243, 810 with GCF Formula
Least Common Multiple (LCM) of 243,810 is 2430
| 3 | 243, 810 |
| 3 | 81, 270 |
| 3 | 27, 90 |
| 3 | 9, 30 |
| 3, 10 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 3 x 3 x 10 = 2430
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 243,810 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(243,810) = 81
common factors(in case of two or more numbers have common factors) = 1
GCF(243,810) x common factors =81 x 1 = 81
LCM(243,810) = ( 243 × 810 ) / 81
LCM(243,810) = 196830 / 81
LCM(243,810) = 2430
∴ Least Common Multiple of 243,810 is 2430
