To determine if 3285 is a prime number or a composite number, we simply look at the factors for 3285.
If the factors of 3285 are only 3285 and 1, then we know that 3285 is a prime number. Otherwise, 3285 is a composite number.
To explain better, if 3285 is only divisible by 1 and 3285, then it is a prime number, and if 3285 is divisible by more than 3285 and 1, then it is a composite number.
The factors of 3285 are as follows:
1, 3, 5, 9, 15, 45, 73, 219, 365, 657, 1095, 3285
Therefore, since 3285 is divisible by more than one and itself, the answer to the
question "Is 3285 prime or composite?" is highlighted in blue below.
