To determine if 8425 is a prime number or a composite number, we simply look at the factors for 8425.
If the factors of 8425 are only 8425 and 1, then we know that 8425 is a prime number. Otherwise, 8425 is a composite number.
To explain better, if 8425 is only divisible by 1 and 8425, then it is a prime number, and if 8425 is divisible by more than 8425 and 1, then it is a composite number.
The factors of 8425 are as follows:
1, 5, 25, 337, 1685, 8425
Therefore, since 8425 is divisible by more than one and itself, the answer to the
