To determine if 2106 is a prime number or a composite number, we simply look at the factors for 2106.
If the factors of 2106 are only 2106 and 1, then we know that 2106 is a prime number. Otherwise, 2106 is a composite number.
To explain better, if 2106 is only divisible by 1 and 2106, then it is a prime number, and if 2106 is divisible by more than 2106 and 1, then it is a composite number.
The factors of 2106 are as follows:
1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 81, 117, 162, 234, 351, 702, 1053, 2106
Therefore, since 2106 is divisible by more than one and itself, the answer to the
question "Is 2106 prime or composite?" is highlighted in blue below.
composite
Is 2107 prime or composite?
