Is 186 a prime number or a composite number?
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. 186 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: 1 + 8 + 6 = 15. If the sum of the digits is divisible by 3, the number is also divisible by 3.) Also, it is an even number and thus divisible by 2. Therefore, 186 is a composite number.
