To determine if 7986 is a prime number or a composite number, we simply look at the factors for 7986.
If the factors of 7986 are only 7986 and 1, then we know that 7986 is a prime number. Otherwise, 7986 is a composite number.
To explain better, if 7986 is only divisible by 1 and 7986, then it is a prime number, and if 7986 is divisible by more than 7986 and 1, then it is a composite number.
The factors of 7986 are as follows:
1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726, 1331, 2662, 3993, 7986
Therefore, since 7986 is divisible by more than one and itself, the answer to the
question "Is 7986 prime or composite?" is highlighted in blue below.
