To determine if 6890 is a prime number or a composite number, we simply look at the factors for 6890.
If the factors of 6890 are only 6890 and 1, then we know that 6890 is a prime number. Otherwise, 6890 is a composite number.
To explain better, if 6890 is only divisible by 1 and 6890, then it is a prime number, and if 6890 is divisible by more than 6890 and 1, then it is a composite number.
The factors of 6890 are as follows:
1, 2, 5, 10, 13, 26, 53, 65, 106, 130, 265, 530, 689, 1378, 3445, 6890
Therefore, since 6890 is divisible by more than one and itself, the answer to the
question "Is 6890 prime or composite?" is highlighted in blue below.
composite
Is 6891 prime or composite?
