To determine if 6516 is a prime number or a composite number, we simply look at the factors for 6516.
If the factors of 6516 are only 6516 and 1, then we know that 6516 is a prime number. Otherwise, 6516 is a composite number.
To explain better, if 6516 is only divisible by 1 and 6516, then it is a prime number, and if 6516 is divisible by more than 6516 and 1, then it is a composite number.
The factors of 6516 are as follows:
1, 2, 3, 4, 6, 9, 12, 18, 36, 181, 362, 543, 724, 1086, 1629, 2172, 3258, 6516
Therefore, since 6516 is divisible by more than one and itself, the answer to the
question "Is 6516 prime or composite?" is highlighted in blue below.
composite
Is 6517 prime or composite?
