To determine if 7904 is a prime number or a composite number, we simply look at the factors for 7904.
If the factors of 7904 are only 7904 and 1, then we know that 7904 is a prime number. Otherwise, 7904 is a composite number.
To explain better, if 7904 is only divisible by 1 and 7904, then it is a prime number, and if 7904 is divisible by more than 7904 and 1, then it is a composite number.
The factors of 7904 are as follows:
1, 2, 4, 8, 13, 16, 19, 26, 32, 38, 52, 76, 104, 152, 208, 247, 304, 416, 494, 608, 988, 1976, 3952, 7904
Therefore, since 7904 is divisible by more than one and itself, the answer to the
question "Is 7904 prime or composite?" is highlighted in blue below.
