1. Find Factors of 72 by Multiplication method
Solution:
In Multiplication method, If we can express 72 as the product of two numbers, then the numbers being multiplied are factors of 72
| 1 | `xx` | 72 | = | 72 | | 2 | `xx` | 36 | = | 72 | | 3 | `xx` | 24 | = | 72 | | 4 | `xx` | 18 | = | 72 | | 6 | `xx` | 12 | = | 72 | | 8 | `xx` | 9 | = | 72 | | 9 | `xx` | 8 | = | 72 |
Since 9 and 8 are already factors of 72, so we stop here
So, factors of 72 are
`1,2,3,4,6,8,9,12,18,24,36,72`
