To determine if 890 is a prime number or a composite number, we simply look at the factors for 890.
If the factors of 890 are only 890 and 1, then we know that 890 is a prime number. Otherwise, 890 is a composite number.
To explain better, if 890 is only divisible by 1 and 890, then it is a prime number, and if 890 is divisible by more than 890 and 1, then it is a composite number.
The factors of 890 are as follows:
1, 2, 5, 10, 89, 178, 445, 890
Therefore, since 890 is divisible by more than one and itself, the answer to the
question "Is 890 prime or composite?" is highlighted in blue below.
composite
Is 891 prime or composite?
