1. Find Factors of 72 by Division method
Solution:
In Division method, 72 is divided by different integers. If the integers divide 72 exactly and leave the remainder 0, then those integers are considered as the factors of 72.
| 72 | `-:` | 1 | = | 72 | | 72 | `-:` | 2 | = | 36 | | 72 | `-:` | 3 | = | 24 | | 72 | `-:` | 4 | = | 18 | | 72 | `-:` | 6 | = | 12 | | 72 | `-:` | 8 | = | 9 | | 72 | `-:` | 9 | = | 8 |
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`
