To determine if 2144 is a prime number or a composite number, we simply look at the factors for 2144.
If the factors of 2144 are only 2144 and 1, then we know that 2144 is a prime number. Otherwise, 2144 is a composite number.
To explain better, if 2144 is only divisible by 1 and 2144, then it is a prime number, and if 2144 is divisible by more than 2144 and 1, then it is a composite number.
The factors of 2144 are as follows:
1, 2, 4, 8, 16, 32, 67, 134, 268, 536, 1072, 2144
Therefore, since 2144 is divisible by more than one and itself, the answer to the
question "Is 2144 prime or composite?" is highlighted in blue below.
