To determine if 2127 is a prime number or a composite number, we simply look at the factors for 2127.
If the factors of 2127 are only 2127 and 1, then we know that 2127 is a prime number. Otherwise, 2127 is a composite number.
To explain better, if 2127 is only divisible by 1 and 2127, then it is a prime number, and if 2127 is divisible by more than 2127 and 1, then it is a composite number.
The factors of 2127 are as follows:
1, 3, 709, 2127
Therefore, since 2127 is divisible by more than one and itself, the answer to the
question "Is 2127 prime or composite?" is highlighted in blue below.
