To determine if 1148 is a prime number or a composite number, we simply look at the factors for 1148.
If the factors of 1148 are only 1148 and 1, then we know that 1148 is a prime number. Otherwise, 1148 is a composite number.
To explain better, if 1148 is only divisible by 1 and 1148, then it is a prime number, and if 1148 is divisible by more than 1148 and 1, then it is a composite number.
The factors of 1148 are as follows:
1, 2, 4, 7, 14, 28, 41, 82, 164, 287, 574, 1148
Therefore, since 1148 is divisible by more than one and itself, the answer to the
question "Is 1148 prime or composite?" is highlighted in blue below.
