To determine if 6401 is a prime number or a composite number, we simply look at the factors for 6401.
If the factors of 6401 are only 6401 and 1, then we know that 6401 is a prime number. Otherwise, 6401 is a composite number.
To explain better, if 6401 is only divisible by 1 and 6401, then it is a prime number, and if 6401 is divisible by more than 6401 and 1, then it is a composite number.
The factors of 6401 are as follows:
1, 37, 173, 6401
Therefore, since 6401 is divisible by more than one and itself, the answer to the
question "Is 6401 prime or composite?" is highlighted in blue below.
composite
Is 6402 prime or composite?
