LCM of 15 and 45 is 45
LCM stands for least common multiple. In mathematics, LCM of two numbers 15 and 45, is defined as the smallest positive integer that is divisible by both. It is written as LCM(15, 45).
Hence, LCM of 15 and 45 is 45.
| 3 | 15 45 |
| 3 | 5 15 |
| 5 | 5 5 |
| 1 1 |
Hence, LCM of 15 and 45 is 3 x 3 x 5 = 45.
Hence, LCM of 15 and 45 is 45.
