To determine if 2101 is a prime number or a composite number, we simply look at the factors for 2101.
If the factors of 2101 are only 2101 and 1, then we know that 2101 is a prime number. Otherwise, 2101 is a composite number.
To explain better, if 2101 is only divisible by 1 and 2101, then it is a prime number, and if 2101 is divisible by more than 2101 and 1, then it is a composite number.
The factors of 2101 are as follows:
1, 11, 191, 2101
Therefore, since 2101 is divisible by more than one and itself, the answer to the
question "Is 2101 prime or composite?" is highlighted in blue below.
composite
Is 2102 prime or composite?
OK. Now you know that 2101 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.
