To determine if 7803 is a prime number or a composite number, we simply look at the factors for 7803.
If the factors of 7803 are only 7803 and 1, then we know that 7803 is a prime number. Otherwise, 7803 is a composite number.
To explain better, if 7803 is only divisible by 1 and 7803, then it is a prime number, and if 7803 is divisible by more than 7803 and 1, then it is a composite number.
The factors of 7803 are as follows:
1, 3, 9, 17, 27, 51, 153, 289, 459, 867, 2601, 7803
Therefore, since 7803 is divisible by more than one and itself, the answer to the
question "Is 7803 prime or composite?" is highlighted in blue below.
