To determine if 361 is a prime number or a composite number, we simply look at the factors for 361.
If the factors of 361 are only 361 and 1, then we know that 361 is a prime number. Otherwise, 361 is a composite number.
To explain better, if 361 is only divisible by 1 and 361, then it is a prime number, and if 361 is divisible by more than 361 and 1, then it is a composite number.
The factors of 361 are as follows:
1, 19, 361
Therefore, since 361 is divisible by more than one and itself, the answer to the
question "Is 361 prime or composite?" is highlighted in blue below.
composite
Is 362 prime or composite?
OK. Now you know that 361 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.
