To determine if 8531 is a prime number or a composite number, we simply look at the factors for 8531.
If the factors of 8531 are only 8531 and 1, then we know that 8531 is a prime number. Otherwise, 8531 is a composite number.
To explain better, if 8531 is only divisible by 1 and 8531, then it is a prime number, and if 8531 is divisible by more than 8531 and 1, then it is a composite number.
The factors of 8531 are as follows:
1, 19, 449, 8531
Therefore, since 8531 is divisible by more than one and itself, the answer to the
question "Is 8531 prime or composite?" is highlighted in blue below.
composite
Is 8532 prime or composite?
