A Prime number is a number with two and only two factors: 1 (also known as unity) and itself. 981 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 3. (You can check this by adding the digits of the number: 9 + 8 + 1 = 18. If the sum of the digits is divisible by 3, the number is also divisible by 3.) Therefore, 981 is a composite number.
