To determine if 175 is a prime number or a composite number, we simply look at the factors for 175.
If the factors of 175 are only 175 and 1, then we know that 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 answer to the
question "Is 175 prime or composite?" is highlighted in blue below.
composite
Is 176 prime or composite?
OK. Now you know that 175 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
