Composite Numbers

4, 6, 9, 12, 18, 27, 36, 54, 108 are the composite factors of 108.

A prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other words, it has at least one factor besides 1 and itself. 378 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 2 because it is an even number. Therefore, 378 is a composite number.

Any two numbers who are relatively prime will work
So look at 9 and 4. Neither is prime and their GCD is 1.

You must need two numbers with NO other factors in common.

A prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other words, it has at least one factor besides 1 and itself. 1492 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 2 because it is an even number. Therefore, 1492 is a composite number.

Because 60 is divisible by numbers other than 1 and 60.

60 is divisible by 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

Yes. All non-prime numbers are composite numbers, which simply means a number has one or more prime factors other than 1 and the number itself.
