LCM of 16 and 21 is 336
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 16 and 21.
Hence, LCM of 16 and 21 is 336.
| 2 | 16 21 |
| 2 | 8 21 |
| 2 | 4 21 |
| 2 | 2 21 |
| 3 | 1 21 |
| 7 | 1 7 |
| 1 1 |
Hence, LCM of 16 and 21 is 2 x 2 x 2 x 2 x 3 x 7 = 336.
Hence, LCM of 16 and 21 is 336.
