LCM of 15 and 20 is 60
LCM stands for least common multiple. In mathematics, LCM of two numbers 15 and 20, is defined as the smallest positive integer that is divisible by both. It is written as LCM(15, 20).
Hence, LCM of 15 and 20 is 60.
| 2 | 15 20 |
| 2 | 15 10 |
| 3 | 15 5 |
| 5 | 5 5 |
| 1 1 |
Hence, LCM of 15 and 20 is 2 x 2 x 3 x 5 = 60.
Hence, LCM of 15 and 20 is 60.
Franky and Joy are running on a circular track. They take 15 and 20 minutes respectively to go round once. We need to find out at what time (minimum) they will run together again. For this we need to find the LCM of 15 and 20.So, LCM of 15 and 20 is 60.
