To determine whether the number is prime or composite. If the number is composite, write its prime factorization.
Answer to Problem 8C
The number is prime.
Explanation of Solution
Given Information:
Number 83
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 83 is a prime number or a composite number, simply look at the factors for 83.
If the factors of 83 are only 83 and 1, then 83 is a prime number. Otherwise, 83 is a composite number.
To explain better, if 83 is only divisible by 1 and 83, then it is a prime number, and if 83 is divisible by more than 83 and 1, then it is a composite number.
The factors of 83 are as follows:
1, 83
Therefore, since 83 is divisible by only one and itself, the number is prime.
