To determine if 3165 is a prime number or a composite number, we simply look at the factors for 3165.
If the factors of 3165 are only 3165 and 1, then we know that 3165 is a prime number. Otherwise, 3165 is a composite number.
To explain better, if 3165 is only divisible by 1 and 3165, then it is a prime number, and if 3165 is divisible by more than 3165 and 1, then it is a composite number.
The factors of 3165 are as follows:
1, 3, 5, 15, 211, 633, 1055, 3165
Therefore, since 3165 is divisible by more than one and itself, the answer to the
question "Is 3165 prime or composite?" is highlighted in blue below.
