3. Find Factors of 20 by Multiplication method
Solution:
In Multiplication method, If we can express 20 as the product of two numbers, then the numbers being multiplied are factors of 20
| 1 | `xx` | 20 | = | 20 |
| 2 | `xx` | 10 | = | 20 |
| 4 | `xx` | 5 | = | 20 |
| 5 | `xx` | 4 | = | 20 |
Since 5 and 4 are already factors of 20, so we stop here
So, factors of 20 are
`1,2,4,5,10,20`
