LCM of 6 and 21 is 42
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 6 and 21.
Hence, LCM of 6 and 21 is 42.
| 2 | 6 21 |
| 3 | 3 21 |
| 7 | 1 7 |
| 1 1 |
Hence, LCM of 6 and 21 is 2 x 3 x 7 = 42.
Hence, LCM of 6 and 21 is 42.
