To determine if 431 is a prime number or a composite number, we simply look at the factors for 431.
If the factors of 431 are only 431 and 1, then we know that 431 is a prime number. Otherwise, 431 is a composite number.
To explain better, if 431 is only divisible by 1 and 431, then it is a prime number, and if 431 is divisible by more than 431 and 1, then it is a composite number.
The factors of 431 are as follows:
1, 431
Therefore, since 431 is divisible by only one and itself, the answer to the
question "Is 431 prime or composite?" is highlighted in blue below.
prime
Is 432 prime or composite?
