To determine if 2990 is a prime number or a composite number, we simply look at the factors for 2990.
If the factors of 2990 are only 2990 and 1, then we know that 2990 is a prime number. Otherwise, 2990 is a composite number.
To explain better, if 2990 is only divisible by 1 and 2990, then it is a prime number, and if 2990 is divisible by more than 2990 and 1, then it is a composite number.
The factors of 2990 are as follows:
1, 2, 5, 10, 13, 23, 26, 46, 65, 115, 130, 230, 299, 598, 1495, 2990
Therefore, since 2990 is divisible by more than one and itself, the answer to the
question "Is 2990 prime or composite?" is highlighted in blue below.
composite
Is 2991 prime or composite?
