To determine if 1504 is a prime number or a composite number, we simply look at the factors for 1504.
If the factors of 1504 are only 1504 and 1, then we know that 1504 is a prime number. Otherwise, 1504 is a composite number.
To explain better, if 1504 is only divisible by 1 and 1504, then it is a prime number, and if 1504 is divisible by more than 1504 and 1, then it is a composite number.
The factors of 1504 are as follows:
1, 2, 4, 8, 16, 32, 47, 94, 188, 376, 752, 1504
Therefore, since 1504 is divisible by more than one and itself, the answer to the
question "Is 1504 prime or composite?" is highlighted in blue below.
composite
