LCM of 20 and 70 is 140
LCM stands for least common multiple. In mathematics, LCM of two numbers 20 and 70, is defined as the smallest positive integer that is divisible by both. It is written as LCM(20, 70).
Hence, LCM of 20 and 70 is 140.
| 2 | 20 70 |
| 2 | 10 35 |
| 5 | 5 35 |
| 7 | 1 7 |
| 1 1 |
Hence, LCM of 20 and 70 is 2 x 2 x 5 x 7 = 140.
Hence, LCM of 20 and 70 is 140.
