To determine if 358 is a prime number or a composite number, we simply look at the factors for 358.
If the factors of 358 are only 358 and 1, then we know that 358 is a prime number. Otherwise, 358 is a composite number.
To explain better, if 358 is only divisible by 1 and 358, then it is a prime number, and if 358 is divisible by more than 358 and 1, then it is a composite number.
The factors of 358 are as follows:
1, 2, 179, 358
Therefore, since 358 is divisible by more than one and itself, the answer to the
question "Is 358 prime or composite?" is highlighted in blue below.
composite
Is 359 prime or composite?
OK. Now you know that 358 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.
