To determine if 1365 is a prime number or a composite number, we simply look at the factors for 1365.
If the factors of 1365 are only 1365 and 1, then we know that 1365 is a prime number. Otherwise, 1365 is a composite number.
To explain better, if 1365 is only divisible by 1 and 1365, then it is a prime number, and if 1365 is divisible by more than 1365 and 1, then it is a composite number.
The factors of 1365 are as follows:
1, 3, 5, 7, 13, 15, 21, 35, 39, 65, 91, 105, 195, 273, 455, 1365
Therefore, since 1365 is divisible by more than one and itself, the answer to the
question "Is 1365 prime or composite?" is highlighted in blue below.
composite
Is 1366 prime or composite?
