To determine if 2655 is a prime number or a composite number, we simply look at the factors for 2655.
If the factors of 2655 are only 2655 and 1, then we know that 2655 is a prime number. Otherwise, 2655 is a composite number.
To explain better, if 2655 is only divisible by 1 and 2655, then it is a prime number, and if 2655 is divisible by more than 2655 and 1, then it is a composite number.
The factors of 2655 are as follows:
1, 3, 5, 9, 15, 45, 59, 177, 295, 531, 885, 2655
Therefore, since 2655 is divisible by more than one and itself, the answer to the
question "Is 2655 prime or composite?" is highlighted in blue below.
