To determine if 1185 is a prime number or a composite number, we simply look at the factors for 1185.
If the factors of 1185 are only 1185 and 1, then we know that 1185 is a prime number. Otherwise, 1185 is a composite number.
To explain better, if 1185 is only divisible by 1 and 1185, then it is a prime number, and if 1185 is divisible by more than 1185 and 1, then it is a composite number.
The factors of 1185 are as follows:
1, 3, 5, 15, 79, 237, 395, 1185
Therefore, since 1185 is divisible by more than one and itself, the answer to the
question "Is 1185 prime or composite?" is highlighted in blue below.
