LCM of 30 and 40 is 120
LCM stands for least common multiple. In mathematics, LCM of two numbers 30 and 40, is defined as the smallest positive integer that is divisible by both. It is written as LCM(30, 40).
Hence, LCM of 30 and 40 is 120.
| 2 | 30 40 |
| 2 | 15 20 |
| 2 | 15 10 |
| 3 | 15 5 |
| 5 | 5 5 |
| 1 1 |
Hence, LCM of 30 and 40 is 2 x 2 x 2 x 3 x 5 = 120.
Hence, LCM of 30 and 40 is 120.
