To find whether the number is prime or composite. If the number is composite, write its prime factorization.
Answer to Problem 10C
The number is composite.
Explanation of Solution
Given Information: Number 175
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 175 is a prime number or a composite number, simply look at the factors for 175.
If the factors of 175 are only 175 and 1, then 175 is a prime number. Otherwise, 175 is a composite number.
To explain better, if 175 is only divisible by 1 and 175, then it is a prime number, and if 175 is divisible by more than 175 and 1, then it is a composite number.
The factors of 175 are as follows:
1, 5, 7, 25, 35, 175
Therefore, since 175 is divisible by more than one and itself, the number is composite.
