To determine if 437 is a prime number or a composite number, we simply look at the factors for 437.
If the factors of 437 are only 437 and 1, then we know that 437 is a prime number. Otherwise, 437 is a composite number.
To explain better, if 437 is only divisible by 1 and 437, then it is a prime number, and if 437 is divisible by more than 437 and 1, then it is a composite number.
The factors of 437 are as follows:
1, 19, 23, 437
Therefore, since 437 is divisible by more than one and itself, the answer to the
question "Is 437 prime or composite?" is highlighted in blue below.
composite
Is 438 prime or composite?
