<h3>Using the Divisibility Test Method</h3>

<p>The divisibility method determines whether a number is composite or not. Make use of the<a>divisibility rule</a>of 2 (if the number is even), the divisibility rule of 3 (if the<a>sum</a>of digits is a<a>multiple</a>of 3), and so on. The number 177 is divisible by 3, we use the divisibility rule of 3. Hence, factors of 177 are 1, 3, 59, and 177. </p>
