Answer

Factors: $1, 3, 7, 9, 21$ and $63$

Work Step by Step

Start with the number $1$. Divide $63$ by $1$. The result is $63$. $63=1\cdot 63$ $1$ and $63$ are factors of $63$. Divide $63$ by $2$. The result is $31.5$ (not a whole number). $2$ does not divide evenly into $63$. Divide $63$ by $3$. The result is $21$. $63=3\cdot 21$ $3$ and $21$ are additional factors of $63$. Divide $63$ by $4$. The result is $15.75$ (not a whole number). $4$ does not divide evenly into $63$. Divide $63$ by $5$. The result is $12.6$ (not a whole number). $5$ does not divide evenly into $63$. Divide $63$ by $6$. The result is $10.5$ (not a whole number). $6$ does not divide evenly into $63$. Divide $63$ by $7$. The result is $9$. $63=7\cdot 9$ $7$ and $9$ are more factors of $63$. Thus, the factors of $63$ are $1, 3, 7, 9, 21$ and $63$.
