To determine if 7404 is a prime number or a composite number, we simply look at the factors for 7404.
If the factors of 7404 are only 7404 and 1, then we know that 7404 is a prime number. Otherwise, 7404 is a composite number.
To explain better, if 7404 is only divisible by 1 and 7404, then it is a prime number, and if 7404 is divisible by more than 7404 and 1, then it is a composite number.
The factors of 7404 are as follows:
1, 2, 3, 4, 6, 12, 617, 1234, 1851, 2468, 3702, 7404
Therefore, since 7404 is divisible by more than one and itself, the answer to the
question "Is 7404 prime or composite?" is highlighted in blue below.
