To determine if 6531 is a prime number or a composite number, we simply look at the factors for 6531.
If the factors of 6531 are only 6531 and 1, then we know that 6531 is a prime number. Otherwise, 6531 is a composite number.
To explain better, if 6531 is only divisible by 1 and 6531, then it is a prime number, and if 6531 is divisible by more than 6531 and 1, then it is a composite number.
The factors of 6531 are as follows:
1, 3, 7, 21, 311, 933, 2177, 6531
Therefore, since 6531 is divisible by more than one and itself, the answer to the
question "Is 6531 prime or composite?" is highlighted in blue below.
