To determine if 1145 is a prime number or a composite number, we simply look at the factors for 1145.
If the factors of 1145 are only 1145 and 1, then we know that 1145 is a prime number. Otherwise, 1145 is a composite number.
To explain better, if 1145 is only divisible by 1 and 1145, then it is a prime number, and if 1145 is divisible by more than 1145 and 1, then it is a composite number.
The factors of 1145 are as follows:
1, 5, 229, 1145
Therefore, since 1145 is divisible by more than one and itself, the answer to the
question "Is 1145 prime or composite?" is highlighted in blue below.
