To determine if 7225 is a prime number or a composite number, we simply look at the factors for 7225.
If the factors of 7225 are only 7225 and 1, then we know that 7225 is a prime number. Otherwise, 7225 is a composite number.
To explain better, if 7225 is only divisible by 1 and 7225, then it is a prime number, and if 7225 is divisible by more than 7225 and 1, then it is a composite number.
The factors of 7225 are as follows:
1, 5, 17, 25, 85, 289, 425, 1445, 7225
Therefore, since 7225 is divisible by more than one and itself, the answer to the
