To determine if 365 is a prime number or a composite number, we simply look at the factors for 365.
If the factors of 365 are only 365 and 1, then we know that 365 is a prime number. Otherwise, 365 is a composite number.
To explain better, if 365 is only divisible by 1 and 365, then it is a prime number, and if 365 is divisible by more than 365 and 1, then it is a composite number.
The factors of 365 are as follows:
1, 5, 73, 365
Therefore, since 365 is divisible by more than one and itself, the answer to the
question "Is 365 prime or composite?" is highlighted in blue below.
composite
Is 366 prime or composite?
OK. Now you know that 365 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.
