To determine if 6500 is a prime number or a composite number, we simply look at the factors for 6500.
If the factors of 6500 are only 6500 and 1, then we know that 6500 is a prime number. Otherwise, 6500 is a composite number.
To explain better, if 6500 is only divisible by 1 and 6500, then it is a prime number, and if 6500 is divisible by more than 6500 and 1, then it is a composite number.
The factors of 6500 are as follows:
1, 2, 4, 5, 10, 13, 20, 25, 26, 50, 52, 65, 100, 125, 130, 250, 260, 325, 500, 650, 1300, 1625, 3250, 6500
Therefore, since 6500 is divisible by more than one and itself, the answer to the
question "Is 6500 prime or composite?" is highlighted in blue below.
composite
Is 6501 prime or composite?
