To determine if 1558 is a prime number or a composite number, we simply look at the factors for 1558.
If the factors of 1558 are only 1558 and 1, then we know that 1558 is a prime number. Otherwise, 1558 is a composite number.
To explain better, if 1558 is only divisible by 1 and 1558, then it is a prime number, and if 1558 is divisible by more than 1558 and 1, then it is a composite number.
The factors of 1558 are as follows:
1, 2, 19, 38, 41, 82, 779, 1558
Therefore, since 1558 is divisible by more than one and itself, the answer to the
question "Is 1558 prime or composite?" is highlighted in blue below.
