To determine if 3225 is a prime number or a composite number, we simply look at the factors for 3225.
If the factors of 3225 are only 3225 and 1, then we know that 3225 is a prime number. Otherwise, 3225 is a composite number.
To explain better, if 3225 is only divisible by 1 and 3225, then it is a prime number, and if 3225 is divisible by more than 3225 and 1, then it is a composite number.
The factors of 3225 are as follows:
1, 3, 5, 15, 25, 43, 75, 129, 215, 645, 1075, 3225
Therefore, since 3225 is divisible by more than one and itself, the answer to the
question "Is 3225 prime or composite?" is highlighted in blue below.
composite
