To determine if 2870 is a prime number or a composite number, we simply look at the factors for 2870.
If the factors of 2870 are only 2870 and 1, then we know that 2870 is a prime number. Otherwise, 2870 is a composite number.
To explain better, if 2870 is only divisible by 1 and 2870, then it is a prime number, and if 2870 is divisible by more than 2870 and 1, then it is a composite number.
The factors of 2870 are as follows:
1, 2, 5, 7, 10, 14, 35, 41, 70, 82, 205, 287, 410, 574, 1435, 2870
Therefore, since 2870 is divisible by more than one and itself, the answer to the
question "Is 2870 prime or composite?" is highlighted in blue below.
composite
Is 2871 prime or composite?
OK. Now you know that 2870 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
