To determine if 3455 is a prime number or a composite number, we simply look at the factors for 3455.
If the factors of 3455 are only 3455 and 1, then we know that 3455 is a prime number. Otherwise, 3455 is a composite number.
To explain better, if 3455 is only divisible by 1 and 3455, then it is a prime number, and if 3455 is divisible by more than 3455 and 1, then it is a composite number.
The factors of 3455 are as follows:
