To determine if 6404 is a prime number or a composite number, we simply look at the factors for 6404.
If the factors of 6404 are only 6404 and 1, then we know that 6404 is a prime number. Otherwise, 6404 is a composite number.
To explain better, if 6404 is only divisible by 1 and 6404, then it is a prime number, and if 6404 is divisible by more than 6404 and 1, then it is a composite number.
The factors of 6404 are as follows:
1, 2, 4, 1601, 3202, 6404
Therefore, since 6404 is divisible by more than one and itself, the answer to the
question "Is 6404 prime or composite?" is highlighted in blue below.
