LCM of 28 and 40 is 280
The least common multiple or LCM of two numbers 28 and 40 is defined as the smallest positive integer which is divisible by both of them. It is represented by LCM(28, 40).
Hence, LCM of 28 and 40 is 280.
| 2 | 28 40 |
| 2 | 14 20 |
| 2 | 7 10 |
| 5 | 7 5 |
| 7 | 7 1 |
| 1 1 |
Hence, LCM of 28 and 40 is 2 x 2 x 2 x 5 x 7 = 280.
Hence, LCM of 28 and 40 is 280.
