<p>To determine if a number is prime, check its divisibility by smaller prime numbers. If it is divisible by any of them, it is not prime. Example: Check if 439 is a prime number.</p>
25
<p><strong>Step 1:</strong>439 ÷ 2 = 219.5 (<a>remainder</a>≠ 0)</p>
24
<p><strong>Step 1:</strong>439 ÷ 2 = 219.5 (<a>remainder</a>≠ 0)</p>
26
<p><strong>Step 2:</strong>439 ÷ 3 = 146.33 (remainder ≠ 0)</p>

<p><strong>Step 2:</strong>439 ÷ 3 = 146.33 (remainder ≠ 0)</p>
27
<p><strong>Step 3:</strong>439 ÷ 5 = 87.8 (remainder ≠ 0)</p>
26
<p><strong>Step 3:</strong>439 ÷ 5 = 87.8 (remainder ≠ 0)</p>

<p><strong>Step 5:</strong>5 ÷ 5 = 1 (5 is prime)</p>
36
<p>Therefore, the prime factorization of 450 is 2 × 32 × 52.</p>
