To determine if 1788 is a prime number or a composite number, we simply look at the factors for 1788.
If the factors of 1788 are only 1788 and 1, then we know that 1788 is a prime number. Otherwise, 1788 is a composite number.
To explain better, if 1788 is only divisible by 1 and 1788, then it is a prime number, and if 1788 is divisible by more than 1788 and 1, then it is a composite number.
The factors of 1788 are as follows:
1, 2, 3, 4, 6, 12, 149, 298, 447, 596, 894, 1788
Therefore, since 1788 is divisible by more than one and itself, the answer to the
question "Is 1788 prime or composite?" is highlighted in blue below.
