To determine if 429 is a prime number or a composite number, we simply look at the factors for 429.
If the factors of 429 are only 429 and 1, then we know that 429 is a prime number. Otherwise, 429 is a composite number.
To explain better, if 429 is only divisible by 1 and 429, then it is a prime number, and if 429 is divisible by more than 429 and 1, then it is a composite number.
The factors of 429 are as follows:
1, 3, 11, 13, 33, 39, 143, 429
Therefore, since 429 is divisible by more than one and itself, the answer to the
question "Is 429 prime or composite?" is highlighted in blue below.
composite
Is 430 prime or composite?
