To determine if 2146 is a prime number or a composite number, we simply look at the factors for 2146.
If the factors of 2146 are only 2146 and 1, then we know that 2146 is a prime number. Otherwise, 2146 is a composite number.
To explain better, if 2146 is only divisible by 1 and 2146, then it is a prime number, and if 2146 is divisible by more than 2146 and 1, then it is a composite number.
The factors of 2146 are as follows:
1, 2, 29, 37, 58, 74, 1073, 2146
Therefore, since 2146 is divisible by more than one and itself, the answer to the
question "Is 2146 prime or composite?" is highlighted in blue below.
