To determine if 2387 is a prime number or a composite number, we simply look at the factors for 2387.
If the factors of 2387 are only 2387 and 1, then we know that 2387 is a prime number. Otherwise, 2387 is a composite number.
To explain better, if 2387 is only divisible by 1 and 2387, then it is a prime number, and if 2387 is divisible by more than 2387 and 1, then it is a composite number.
The factors of 2387 are as follows:
1, 7, 11, 31, 77, 217, 341, 2387
Therefore, since 2387 is divisible by more than one and itself, the answer to the
question "Is 2387 prime or composite?" is highlighted in blue below.
