3. Find Factors of 20 by Division method
Solution:
In Division method, 20 is divided by different integers. If the integers divide 20 exactly and leave the remainder 0, then those integers are considered as the factors of 20.
| 20 | `-:` | 1 | = | 20 |
| 20 | `-:` | 2 | = | 10 |
| 20 | `-:` | 4 | = | 5 |
| 20 | `-:` | 5 | = | 4 |
Since 5 and 4 are already factors of 20, so we stop here
So, factors of 20 are
`1,2,4,5,10,20`
