To determine if 3423 is a prime number or a composite number, we simply look at the factors for 3423.
If the factors of 3423 are only 3423 and 1, then we know that 3423 is a prime number. Otherwise, 3423 is a composite number.
To explain better, if 3423 is only divisible by 1 and 3423, then it is a prime number, and if 3423 is divisible by more than 3423 and 1, then it is a composite number.
The factors of 3423 are as follows:
1, 3, 7, 21, 163, 489, 1141, 3423
