To determine if 8407 is a prime number or a composite number, we simply look at the factors for 8407.
If the factors of 8407 are only 8407 and 1, then we know that 8407 is a prime number. Otherwise, 8407 is a composite number.
To explain better, if 8407 is only divisible by 1 and 8407, then it is a prime number, and if 8407 is divisible by more than 8407 and 1, then it is a composite number.
The factors of 8407 are as follows:
