To determine if 2991 is a prime number or a composite number, we simply look at the factors for 2991.
If the factors of 2991 are only 2991 and 1, then we know that 2991 is a prime number. Otherwise, 2991 is a composite number.
To explain better, if 2991 is only divisible by 1 and 2991, then it is a prime number, and if 2991 is divisible by more than 2991 and 1, then it is a composite number.
The factors of 2991 are as follows:
1, 3, 997, 2991
Therefore, since 2991 is divisible by more than one and itself, the answer to the
question "Is 2991 prime or composite?" is highlighted in blue below.
composite
Is 2992 prime or composite?
