To determine if 1173 is a prime number or a composite number, we simply look at the factors for 1173.
If the factors of 1173 are only 1173 and 1, then we know that 1173 is a prime number. Otherwise, 1173 is a composite number.
To explain better, if 1173 is only divisible by 1 and 1173, then it is a prime number, and if 1173 is divisible by more than 1173 and 1, then it is a composite number.
The factors of 1173 are as follows:
1, 3, 17, 23, 51, 69, 391, 1173
Therefore, since 1173 is divisible by more than one and itself, the answer to the
question "Is 1173 prime or composite?" is highlighted in blue below.
