To determine if 8255 is a prime number or a composite number, we simply look at the factors for 8255.
If the factors of 8255 are only 8255 and 1, then we know that 8255 is a prime number. Otherwise, 8255 is a composite number.
To explain better, if 8255 is only divisible by 1 and 8255, then it is a prime number, and if 8255 is divisible by more than 8255 and 1, then it is a composite number.
The factors of 8255 are as follows:
1, 5, 13, 65, 127, 635, 1651, 8255
Therefore, since 8255 is divisible by more than one and itself, the answer to the
question "Is 8255 prime or composite?" is highlighted in blue below.
