To determine if 6511 is a prime number or a composite number, we simply look at the factors for 6511.
If the factors of 6511 are only 6511 and 1, then we know that 6511 is a prime number. Otherwise, 6511 is a composite number.
To explain better, if 6511 is only divisible by 1 and 6511, then it is a prime number, and if 6511 is divisible by more than 6511 and 1, then it is a composite number.
The factors of 6511 are as follows:
1, 17, 383, 6511
Therefore, since 6511 is divisible by more than one and itself, the answer to the
question "Is 6511 prime or composite?" is highlighted in blue below.
composite
Is 6512 prime or composite?
