<p><strong>Step 1:</strong>All numbers are divisible by 1 and itself.</p>
24
<p><strong>Step 2:</strong>Divide 450 by 2. It is divisible by 2, so 2 is a factor of 450.</p>

<p><strong>Step 2:</strong>Divide 450 by 2. It is divisible by 2, so 2 is a factor of 450.</p>
25
<p><strong>Step 3:</strong>Divide 450 by 3. It is divisible by 3, so 3 is a factor of 450.</p>
25
<p><strong>Step 3:</strong>Divide 450 by 3. It is divisible by 3, so 3 is a factor of 450.</p>
26
<p><strong>Step 4:</strong>You can simplify checking divisors up to 450 by finding the root value. We then need to only check divisors up to the root value.</p>

<p><strong>Divisibility by 5:</strong>The unit’s place digit is 0. Therefore, 450 is divisible by 5.</p>
35
<p><strong>Divisibility by 7:</strong>The last digit in 450 is 0. To check divisibility by 7, double the last digit (0 × 2 = 0). Then, subtract it from the rest of the number (45 - 0 = 45). Since 45 is not divisible by 7, 450 is not divisible by 7.</p>

<p><strong>Divisibility by 11:</strong>In 450, the sum of the digits in odd positions is 4, and the sum of the digits in even positions is 5. This would<a>mean</a>that 450 is not divisible by 11. Since 450 is divisible by 2, 3, and 5, it has more than two factors. Therefore, it is a composite number.</p>
