LCM of 63 and 21 is 63
The least common multiple or LCM of two numbers 63 and 21 is defined as the smallest positive integer which is divisible by both of them. It is represented by LCM(63, 21).
Hence, LCM of 63 and 21 is 63.
| 3 | 63 21 |
| 3 | 21 7 |
| 7 | 7 7 |
| 1 1 |
Hence, LCM of 63 and 21 is 3 x 3 x 7 = 63.
Hence, LCM of 63 and 21 is 63.
