Understanding Composite Numbers and How to Determine If a Number is Composite

Composite numbers are positive integers greater than 1 that have at least one divisor other than 1 and itself

Composite numbers are positive integers greater than 1 that have at least one divisor other than 1 and itself. In other words, composite numbers are those that can be divided evenly by more than two positive integers.

To determine if a number is composite, you can take the following steps:

1. Start with the number you want to check if it is composite.
2. Identify all the positive integers that divide the number without any remainder.
3. If there are more than two divisors, then the number is composite. If there are only two divisors (1 and the number itself), then the number is prime.

For example, let’s say we want to check if the number 12 is composite:

1. Start with the number 12.
2. Identify all the positive integers that divide 12 without any remainder: 1, 2, 3, 4, 6, 12.
3. Since 12 has more than two divisors (1, 2, 3, 4, 6, and 12), it is a composite number.

On the other hand, if we want to check if the number 7 is composite:

1. Start with the number 7.
2. Identify all the positive integers that divide 7 without any remainder: 1, 7.
3. Since 7 only has two divisors (1 and 7), it is a prime number, not composite.

So, composite numbers are positive integers greater than 1 that have more than two divisors.
