To find whether the number is prime or composite.
Answer to Problem 9E
The number is prime.
Explanation of Solution
Given Information:Number 17
Formula used: To check if the numbers is prime or composite by finding its factors. If its factors are more than 2(except 1 and the number itself), then the number is composite else prime.
Calculation:
To determine if 17 is a prime number or a composite number, simply look at the factors for 17.
If the factors of 17 are only 17 and 1, then 17 is a prime number. Otherwise, 17 is a composite number.
To explain better, if 17 is only divisible by 1 and 17, then it is a prime number, and if 17 is divisible by more than 17 and 1, then it is a composite number.
The factors of 17 are as follows:
1, 17
Therefore, since 17 is divisible by only one and itself, the number is prime.
