LCM of 21 and 70 is 210
In mathematics, least common multiple which is commonly known as LCM is defined as the smallest non-zero number which is divisible by both given numbers 21 and 70.
Hence, LCM of 21 and 70 is 210.
| 2 | 21 70 |
| 3 | 21 35 |
| 5 | 7 35 |
| 7 | 7 7 |
| 1 1 |
Hence, LCM of 21 and 70 is 2 x 3 x 5 x 7 = 210.
Hence, LCM of 21 and 70 is 210.
