To find whether the number is prime or composite. If the number is composite, write its prime factorization.

Answer to Problem 6C
The number is composite.
Explanation of Solution
Given Information:
Number 56
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 56 is a prime number or a composite number, simply look at the factors for 56.
If the factors of 56 are only 56 and 1, then 56 is a prime number. Otherwise, 56 is a composite number.
To explain better, if 56 is only divisible by 1 and 56, then it is a prime number, and if 56 is divisible by more than 56 and 1, then it is a composite number.
The factors of 56 are as follows:
1, 2, 4, 7, 8, 14, 28, 56
Therefore, the number is composite.
