For example, the integer $36$ is divisible by, in no particular order, $4$, $1$, $9$, $-6$, etc. All of those numbers are factors of $36$. Notice that negative integers can also be factors, but the GRE usually asks only about positive factors.</p>
<p>Another way to think about factors is, "What numbers multiply together to form an integer." For example, $5 \times 20=100$, so $5$ and $20$ are factors of $100$.</p>
