Introduction to non prime number:
In this section we will study about non prime number. Prime numbers are only divisible by itself and one. The other numbers are called as non prime numbers. The non prime numbers also called as composite numbers. In below we will see about some example and practice problems for composite numbers. Let us study about non prime numbers.
Example Problems for Non Prime Number:
Example problem 1: Is 18 a prime number or a composite number?
Solution:
Given number is 18
The only factors of a prime number are 1 and itself.
A non prime number has more factors than just 1 and itself.
18 have more factors than just 1 and itself.
For example, 2 is a factor of 18:
18 ÷ 2 = 9
Therefore, 18 is not a prime number.
Answer: 18 is a composite number.
Example problem 2: Is 2 a prime number or a composite number?
Solution:
Given number is 2
The only factors of a prime number are 1 and itself.
A non prime number has more factors than just 1 and itself.
The factors of 2 are 1 and 2.
Therefore, 2 is a prime number.
Answer: 2 is a prime number.

Practice Problems for Non Prime Number:
Practice problem 1: Is 11 a prime number or a composite number?
Practice problem 2: Is 13 a prime number or a composite number?
Practice problem 3: Is 15 a prime number or a composite number?
Practice problem 4: Is 4 a prime number or a composite number?
Solutions for non prime number:
Solution 1: The only factors of 11 are 1 and 11. Therefore, 11 is a prime number.
Solution 2: The only factors of 13 are 1 and 13. Therefore, 13 is a prime number.
Solution 3: 15 have more factors than just 1 and itself. Therefore, 15 is a composite number.
Solution 4: 4 is a non prime number.
