LCM of 81 and 18 is 162
In mathematics, least common multiple which is commonly known as LCM is defined as the smallest non-zero number which is divisible by both given numbers 81 and 18.
Hence, LCM of 81 and 18 is 162.
| 2 | 81 18 |
| 3 | 81 9 |
| 3 | 27 3 |
| 3 | 9 1 |
| 3 | 3 1 |
| 1 1 |
Hence, LCM of 81 and 18 is 2 x 3 x 3 x 3 x 3 = 162.
Hence, LCM of 81 and 18 is 162.
