To determine if 1958 is a prime number or a composite number, we simply look at the factors for 1958.
If the factors of 1958 are only 1958 and 1, then we know that 1958 is a prime number. Otherwise, 1958 is a composite number.
To explain better, if 1958 is only divisible by 1 and 1958, then it is a prime number, and if 1958 is divisible by more than 1958 and 1, then it is a composite number.
The factors of 1958 are as follows:
1, 2, 11, 22, 89, 178, 979, 1958
Therefore, since 1958 is divisible by more than one and itself, the answer to the
question "Is 1958 prime or composite?" is highlighted in blue below.
