LCM of 23 and 21 is 483
The least common multiple or LCM of two numbers 23 and 21 is defined as the smallest positive integer which is divisible by both of them. It is represented by LCM(23, 21).
Hence, LCM of 23 and 21 is 483.
| 3 | 23 21 |
| 7 | 23 7 |
| 23 | 23 1 |
| 1 1 |
Hence, LCM of 23 and 21 is 3 x 7 x 23 = 483.
Hence, LCM of 23 and 21 is 483.
