To determine if 3421 is a prime number or a composite number, we simply look at the factors for 3421.
If the factors of 3421 are only 3421 and 1, then we know that 3421 is a prime number. Otherwise, 3421 is a composite number.
To explain better, if 3421 is only divisible by 1 and 3421, then it is a prime number, and if 3421 is divisible by more than 3421 and 1, then it is a composite number.
The factors of 3421 are as follows:
1, 11, 311, 3421
Therefore, since 3421 is divisible by more than one and itself, the answer to the
question "Is 3421 prime or composite?" is highlighted in blue below.
composite
