To determine if 3345 is a prime number or a composite number, we simply look at the factors for 3345.
If the factors of 3345 are only 3345 and 1, then we know that 3345 is a prime number. Otherwise, 3345 is a composite number.
To explain better, if 3345 is only divisible by 1 and 3345, then it is a prime number, and if 3345 is divisible by more than 3345 and 1, then it is a composite number.
The factors of 3345 are as follows:
1, 3, 5, 15, 223, 669, 1115, 3345
Therefore, since 3345 is divisible by more than one and itself, the answer to the
question "Is 3345 prime or composite?" is highlighted in blue below.
