To determine if 2403 is a prime number or a composite number, we simply look at the factors for 2403.
If the factors of 2403 are only 2403 and 1, then we know that 2403 is a prime number. Otherwise, 2403 is a composite number.
To explain better, if 2403 is only divisible by 1 and 2403, then it is a prime number, and if 2403 is divisible by more than 2403 and 1, then it is a composite number.
The factors of 2403 are as follows:
1, 3, 9, 27, 89, 267, 801, 2403
Therefore, since 2403 is divisible by more than one and itself, the answer to the
question "Is 2403 prime or composite?" is highlighted in blue below.
