LCM of 20 and 7 is 140
LCM stands for least common multiple. In mathematics, LCM of two numbers 20 and 7, is defined as the smallest positive integer that is divisible by both. It is written as LCM(20, 7).
Hence, LCM of 20 and 7 is 140.
| 2 | 20 7 |
| 2 | 10 7 |
| 5 | 5 7 |
| 7 | 1 7 |
| 1 1 |
Hence, LCM of 20 and 7 is 2 x 2 x 5 x 7 = 140.
Hence, LCM of 20 and 7 is 140.
