Answer
Factors: $1$, $3$, $9$
Work Step by Step
Start with the number $1$.
Divide $9$ by $1$. The result is $9$.
$9=1\cdot 9$
$1$ and $9$ are factors of $9$.
Since $9$ is not a prime number, we can check for additional factors.
Divide $9$ by $2$. The result is $4.5$ (not a whole number). $2$ does not divide evenly into $9$.
Divide $9$ by $3$. The result is $3$.
$3$ is another factor of $9$.
$9=3\cdot 3$
Since $9$ is not divisible by any number greater than $3$, we have found all the factors.
