To determine if 4381 is a prime number or a composite number, we simply look at the factors for 4381.
If the factors of 4381 are only 4381 and 1, then we know that 4381 is a prime number. Otherwise, 4381 is a composite number.
To explain better, if 4381 is only divisible by 1 and 4381, then it is a prime number, and if 4381 is divisible by more than 4381 and 1, then it is a composite number.
The factors of 4381 are as follows:
1, 13, 337, 4381
Therefore, since 4381 is divisible by more than one and itself, the answer to the
question "Is 4381 prime or composite?" is highlighted in blue below.
