To determine if 9135 is a prime number or a composite number, we simply look at the factors for 9135.
If the factors of 9135 are only 9135 and 1, then we know that 9135 is a prime number. Otherwise, 9135 is a composite number.
To explain better, if 9135 is only divisible by 1 and 9135, then it is a prime number, and if 9135 is divisible by more than 9135 and 1, then it is a composite number.
The factors of 9135 are as follows:
1, 3, 5, 7, 9, 15, 21, 29, 35, 45, 63, 87, 105, 145, 203, 261, 315, 435, 609, 1015, 1305, 1827, 3045, 9135
Therefore, since 9135 is divisible by more than one and itself, the answer to the
question "Is 9135 prime or composite?" is highlighted in blue below.
