EXAMPLES:
Question:
List all the factors of $\,30\,$:
Answer:
$1\,$,$\,30\,$,$\,2\,$,$\,15\,$,$\,3\,$,$\,10\,$,$\,5\,$,$\,6\,$
For the computer to recognize your answer as correct,
you must list the factors in the order
indicated in the example:
 The factors occur in pairs that multiply together to give $\,30$

$1\,$ goes into $\,30\,$ evenly, giving the pair $\,1\,$,$\,30\,$.
You must write the smaller number first in each pair.

$2\,$ goes into $\,30\,$ evenly, giving the pair $\,2\,$,$\,15\,$

$3\,$ goes into $\,30\,$ evenly, giving the pair $\,3\,$,$\,10\,$

$4\,$ doesn't go into $\,30\,$ evenly

$5\,$ goes into $\,30\,$ evenly, giving the pair $\,5\,$,$\,6\,$
 For this example, these are all the factors.
 The numbers must be separated by commas; spaces are optional.
Question:
List all the factors of $\,25\,$:
Answer:
$1\,$,$\,25\,$,$\,5\,$
Only list the factor $\,5\,$ once.
