Composite numbers are positive integers that have more than two distinct positive divisors. In other words, a composite number can be divided evenly by numbers other than 1 and itself. This means that composite numbers can be formed by multiplying two or more integers together, making them non-prime.
In mathematics, composite numbers come in two primary varieties:
- Even Composite Numbers
- Odd Composite Numbers
Even Composite Numbers
Even composite number refers to a composite number that is also even. Therefore, every even number other than 2 is an even composite number. The lowest even composite number is 4.
Examples are 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30.
Odd Composite Numbers
Odd composite numbers refer to composite numbers that are also odd. It consists of all odd integers that are not prime numbers. 9 is the smallest odd composite number.
Examples are 9, 15, 21, 25, and 27. The composite numbers that are not divisible by two are those listed here. Thus, these five numbers are odd composite numbers if we take into account all the integers between 1 and 30.
1 is neither composite nor prime. As it has only one divisor (itself), it does not meet the requirements for a prime number or composite number. .
