Since 12 is divisible by 3, 57 is divisible by 3.<\/li>\n\n\n\n<li>Dividing 57 by 3 gives 57\u00f73=1957 \u00f7 3 = 1957\u00f73=19.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Factoring<\/strong>: We found that 57 can be factored as 57=3\u00d71957 = 3 \u00d7 1957=3\u00d719. Since 57 has divisors other than 1 and itself (specifically 3 and 19), it is a <strong>composite number<\/strong>.<\/li>\n<\/ol>\n\n\n\n<p>Thus, <strong>57 is a composite number<\/strong> because it has more than two divisors: 1, 3, 19, and 57.<\/p>\n\n\n\n<p>In summary, <strong>prime numbers<\/strong> only have divisors of 1 and the number itself, whereas <strong>composite numbers<\/strong> have more divisors.
