To determine if 3540 is a prime number or a composite number, we simply look at the factors for 3540.
If the factors of 3540 are only 3540 and 1, then we know that 3540 is a prime number. Otherwise, 3540 is a composite number.
To explain better, if 3540 is only divisible by 1 and 3540, then it is a prime number, and if 3540 is divisible by more than 3540 and 1, then it is a composite number.
The factors of 3540 are as follows:
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 59, 60, 118, 177, 236, 295, 354, 590, 708, 885, 1180, 1770, 3540
Therefore, since 3540 is divisible by more than one and itself, the answer to the
question "Is 3540 prime or composite?" is highlighted in blue below.
composite
Is 3541 prime or composite?
