To determine if 6486 is a prime number or a composite number, we simply look at the factors for 6486.
If the factors of 6486 are only 6486 and 1, then we know that 6486 is a prime number. Otherwise, 6486 is a composite number.
To explain better, if 6486 is only divisible by 1 and 6486, then it is a prime number, and if 6486 is divisible by more than 6486 and 1, then it is a composite number.
The factors of 6486 are as follows:
1, 2, 3, 6, 23, 46, 47, 69, 94, 138, 141, 282, 1081, 2162, 3243, 6486
Therefore, since 6486 is divisible by more than one and itself, the answer to the
question "Is 6486 prime or composite?" is highlighted in blue below.
