To determine if 7285 is a prime number or a composite number, we simply look at the factors for 7285.
If the factors of 7285 are only 7285 and 1, then we know that 7285 is a prime number. Otherwise, 7285 is a composite number.
To explain better, if 7285 is only divisible by 1 and 7285, then it is a prime number, and if 7285 is divisible by more than 7285 and 1, then it is a composite number.
The factors of 7285 are as follows:
1, 5, 31, 47, 155, 235, 1457, 7285
