<p><strong>Step 2:</strong>Leave 1 without coloring or crossing, as it is neither prime nor composite. </p>

<p><strong>Step 5:</strong>Repeat this process until you reach the table consisting of marked and crossed boxes, except 1. Through this process, we will have a list of prime numbers from 1 to 100. The list is 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, and 97. 230 is not present in the list of prime numbers, so it is a composite number.</p>
