<p>Factors are the ‘building blocks’ of a number. They are the numbers that can be multiplied together to reach the number you started with. 289 is an interesting number. It is large enough to make you think, but simple enough to learn if you know a few tricks. Let’s dive into it!</p>

52
<p>Divide 289 by 13: 289÷13=22.23</p>
53
<p>Since 22.23 is not a whole number, 13 is not a factor of 289. </p>

<h3>Explanation</h3>
55
<p>To check divisibility, divide 289 by 13. If the result is a whole number, 13 would be a factor. Since 13 does not divide 289 evenly, it’s not a factor. </p>
