To determine if 6750 is a prime number or a composite number, we simply look at the factors for 6750.
If the factors of 6750 are only 6750 and 1, then we know that 6750 is a prime number. Otherwise, 6750 is a composite number.
To explain better, if 6750 is only divisible by 1 and 6750, then it is a prime number, and if 6750 is divisible by more than 6750 and 1, then it is a composite number.
The factors of 6750 are as follows:
1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 27, 30, 45, 50, 54, 75, 90, 125, 135, 150, 225, 250, 270, 375, 450, 675, 750, 1125, 1350, 2250, 3375, 6750
Therefore, since 6750 is divisible by more than one and itself, the answer to the
question "Is 6750 prime or composite?" is highlighted in blue below.
composite
Is 6751 prime or composite?
