To determine if 2890 is a prime number or a composite number, we simply look at the factors for 2890.
If the factors of 2890 are only 2890 and 1, then we know that 2890 is a prime number. Otherwise, 2890 is a composite number.
To explain better, if 2890 is only divisible by 1 and 2890, then it is a prime number, and if 2890 is divisible by more than 2890 and 1, then it is a composite number.
The factors of 2890 are as follows:
1, 2, 5, 10, 17, 34, 85, 170, 289, 578, 1445, 2890
Therefore, since 2890 is divisible by more than one and itself, the answer to the
question "Is 2890 prime or composite?" is highlighted in blue below.
composite
Is 2891 prime or composite?
