To determine if 369 is a prime number or a composite number, we simply look at the factors for 369.
If the factors of 369 are only 369 and 1, then we know that 369 is a prime number. Otherwise, 369 is a composite number.
To explain better, if 369 is only divisible by 1 and 369, then it is a prime number, and if 369 is divisible by more than 369 and 1, then it is a composite number.
The factors of 369 are as follows:
1, 3, 9, 41, 123, 369
Therefore, since 369 is divisible by more than one and itself, the answer to the
question "Is 369 prime or composite?" is highlighted in blue below.
composite
Is 370 prime or composite?
OK. Now you know that 369 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.
