Smallest Odd Composite Number

An odd composite number is a number that is not prime (not divisible by only 1 and itself) and is also an odd number. In other words, it is a positive integer greater than 1 that is not prime.

Odd Numbers

Odd numbers are integers that are not divisible evenly by 2. They can be represented in the form 2n + 1, where n is an integer. For example, 1, 3, 5, 7, 9, etc., are all odd numbers.

Composite Numbers

Composite numbers are positive integers that have factors other than 1 and itself. In other words, they can be divided evenly by at least one number other than 1 and itself. For example, 4, 6, 8, 9, 10, etc., are all composite numbers.

Smallest Odd Composite Number

To find the smallest odd composite number, we need to consider odd numbers greater than 1 and check whether they are composite or not. Starting from 3, we can check each odd number one by one.

Let's consider the number 3. It is an odd number, but it is not composite as it is a prime number.

Next, we consider the number 5. It is an odd number, and it is also composite as it can be divided evenly by 1 and 5.

Therefore, the smallest odd composite number is 5.
