To determine if 3255 is a prime number or a composite number, we simply look at the factors for 3255.
If the factors of 3255 are only 3255 and 1, then we know that 3255 is a prime number. Otherwise, 3255 is a composite number.
To explain better, if 3255 is only divisible by 1 and 3255, then it is a prime number, and if 3255 is divisible by more than 3255 and 1, then it is a composite number.
The factors of 3255 are as follows:
1, 3, 5, 7, 15, 21, 31, 35, 93, 105, 155, 217, 465, 651, 1085, 3255
Therefore, since 3255 is divisible by more than one and itself, the answer to the
question "Is 3255 prime or composite?" is highlighted in blue below.
composite
Is 3256 prime or composite?
