To determine if 838 is a prime number or a composite number, we simply look at the factors for 838.
If the factors of 838 are only 838 and 1, then we know that 838 is a prime number. Otherwise, 838 is a composite number.
To explain better, if 838 is only divisible by 1 and 838, then it is a prime number, and if 838 is divisible by more than 838 and 1, then it is a composite number.
The factors of 838 are as follows:
1, 2, 419, 838
Therefore, since 838 is divisible by more than one and itself, the answer to the
question "Is 838 prime or composite?" is highlighted in blue below.
composite
Is 839 prime or composite?
