To determine if 8040 is a prime number or a composite number, we simply look at the factors for 8040.
If the factors of 8040 are only 8040 and 1, then we know that 8040 is a prime number. Otherwise, 8040 is a composite number.
To explain better, if 8040 is only divisible by 1 and 8040, then it is a prime number, and if 8040 is divisible by more than 8040 and 1, then it is a composite number.
The factors of 8040 are as follows:
1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 67, 120, 134, 201, 268, 335, 402, 536, 670, 804, 1005, 1340, 1608, 2010, 2680, 4020, 8040
Therefore, since 8040 is divisible by more than one and itself, the answer to the
question "Is 8040 prime or composite?" is highlighted in blue below.
composite
Is 8041 prime or composite?
