To determine if 2985 is a prime number or a composite number, we simply look at the factors for 2985.
If the factors of 2985 are only 2985 and 1, then we know that 2985 is a prime number. Otherwise, 2985 is a composite number.
To explain better, if 2985 is only divisible by 1 and 2985, then it is a prime number, and if 2985 is divisible by more than 2985 and 1, then it is a composite number.
The factors of 2985 are as follows:
1, 3, 5, 15, 199, 597, 995, 2985
Therefore, since 2985 is divisible by more than one and itself, the answer to the
question "Is 2985 prime or composite?" is highlighted in blue below.
