To determine if 6431 is a prime number or a composite number, we simply look at the factors for 6431.
If the factors of 6431 are only 6431 and 1, then we know that 6431 is a prime number. Otherwise, 6431 is a composite number.
To explain better, if 6431 is only divisible by 1 and 6431, then it is a prime number, and if 6431 is divisible by more than 6431 and 1, then it is a composite number.
The factors of 6431 are as follows:
1, 59, 109, 6431
Therefore, since 6431 is divisible by more than one and itself, the answer to the
question "Is 6431 prime or composite?" is highlighted in blue below.
