To determine if 1658 is a prime number or a composite number, we simply look at the factors for 1658.
If the factors of 1658 are only 1658 and 1, then we know that 1658 is a prime number. Otherwise, 1658 is a composite number.
To explain better, if 1658 is only divisible by 1 and 1658, then it is a prime number, and if 1658 is divisible by more than 1658 and 1, then it is a composite number.
The factors of 1658 are as follows:
1, 2, 829, 1658
Therefore, since 1658 is divisible by more than one and itself, the answer to the
question "Is 1658 prime or composite?" is highlighted in blue below.
