To determine if 2921 is a prime number or a composite number, we simply look at the factors for 2921.
If the factors of 2921 are only 2921 and 1, then we know that 2921 is a prime number. Otherwise, 2921 is a composite number.
To explain better, if 2921 is only divisible by 1 and 2921, then it is a prime number, and if 2921 is divisible by more than 2921 and 1, then it is a composite number.
The factors of 2921 are as follows:
1, 23, 127, 2921
Therefore, since 2921 is divisible by more than one and itself, the answer to the
question "Is 2921 prime or composite?" is highlighted in blue below.
