To determine if 1144 is a prime number or a composite number, we simply look at the factors for 1144.
If the factors of 1144 are only 1144 and 1, then we know that 1144 is a prime number. Otherwise, 1144 is a composite number.
To explain better, if 1144 is only divisible by 1 and 1144, then it is a prime number, and if 1144 is divisible by more than 1144 and 1, then it is a composite number.
The factors of 1144 are as follows:
1, 2, 4, 8, 11, 13, 22, 26, 44, 52, 88, 104, 143, 286, 572, 1144
Therefore, since 1144 is divisible by more than one and itself, the answer to the
question "Is 1144 prime or composite?" is highlighted in blue below.
composite
Is 1145 prime or composite?
