<p><strong>Step 2:</strong>Now divide 420 by 2 to get 210.</p>
4
<p><strong>Step 3:</strong>Then divide 210 by 2 to get 105.</p>

<p><strong>Step 4:</strong>Divide 105 by 3 to get 35.</p>
6
<p><strong>Step 5:</strong>Divide 35 by 5 to get 7. Here, 7 is the smallest prime number that cannot be divided anymore. So, the prime factorization of -420 is: -1 × 2² × 3 × 5 × 7.</p>
