A composite number is a positive integer. which is not prime (i.e., which has factors other than 1 and itself). The first few composite numbers (sometimes called "composites" for short) are 4, 6, 8, 9, 10, 12, 14, 15, 16, ...

What is composite number example?

All the even numbers which are not prime are even composite numbers. For example, 4, 6, 8, 10, 12, 14, 16, are even composite numbers. Consider the numbers 1, 2, 3, 4, 9, 10, 11, 12 and 15 again. Here 4, 10, and 12 are the even composites because they have even divisors and satisfy the composite condition.

What is a composite number for kids?

Composite numbers are whole numbers that can be divided by numbers other than itself and 1. They have “factors.” Factors are the numbers that divide into it. For example, 2 and 5 are factors of 10. Every whole number higher than 1 is either a composite number or a prime number.

How do you find a composite number?

1. Find all factors of the number.
2. If the number has only two factors, 1 and itself, then it is prime.
3. If the number has more than two factors, then it is composite.
