A positive integer that can be generated by multiplying two smaller positive integers is a composite number. All composite numbers can be written as the product of two or more primes. For example, an integer 21 is a composite number as it is the product of the two smaller integers 3 and 7.

FAQ (Frequently Asked Questions)

Q: What are Composite Numbers?

A: Composite numbers can be defined in Math as the whole numbers that have more than two factors. Composite numbers are not prime, since they are divisible by more than two numbers.

Q: What is the Smallest Odd Composite Number and Smallest Even Composite Number?

A: The smallest odd composite number is 9 and the smallest even composite number is 4.

Q: Explain Why 0 and 1 are Neither Prime Nor Composite.

A: 0 and 1 are neither composite nor prime. They are too distinctive because they reflect nothingness (zero) and wholeness (one), so there is no sense in the concept of having factors for 0 and 1. For instance, all even numbers are divisible by 2, and so composite numbers are all even numbers greater than 2.
