To determine if 7788 is a prime number or a composite number, we simply look at the factors for 7788.
If the factors of 7788 are only 7788 and 1, then we know that 7788 is a prime number. Otherwise, 7788 is a composite number.
To explain better, if 7788 is only divisible by 1 and 7788, then it is a prime number, and if 7788 is divisible by more than 7788 and 1, then it is a composite number.
The factors of 7788 are as follows:
1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 59, 66, 118, 132, 177, 236, 354, 649, 708, 1298, 1947, 2596, 3894, 7788
Therefore, since 7788 is divisible by more than one and itself, the answer to the
question "Is 7788 prime or composite?" is highlighted in blue below.
