<p><strong>Step 2:</strong>Now divide 405 by 3 to get 135.</p>
4
<p><strong>Step 3:</strong>Then divide 135 by 3 to get 45.</p>

<p><strong>Step 3:</strong>Then divide 135 by 3 to get 45.</p>
5
<p><strong>Step 4:</strong>Divide 45 by 3 to get 15.</p>
5
<p><strong>Step 4:</strong>Divide 45 by 3 to get 15.</p>
6
<p><strong>Step 5:</strong>Divide 15 by 3 to get 5. Here, 5 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 1215 is: 35 × 5.</p>
