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.
1536 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 2. (You can determine this by looking at the final digit of the number. If it is even, in other words, if it is 0, 2, 4, 6, or 8, the number is divisible by 2.) Therefore, 1536 is a composite number.
It is not a prime number, it is a composite number.
