put this solution on YOUR website!To find factors of a number N it is enough to search the odd numbers from 3-
. The table below whether or not a number is a factor of 499 by checking whether or not 499/n has a remainder (you will need to scroll down to see the table).
| n | remainder |
| 3 | yes |
| 7 | yes |
| 13 | yes |
| 17 | yes |
| 19 | yes |
| 21 | yes |
Since 499 has no factors, it must be prime. I skipped some possible values like 5 and 9. Do you know why?
