To determine if 5643 is a prime number or a composite number, we simply look at the factors for 5643.
If the factors of 5643 are only 5643 and 1, then we know that 5643 is a prime number. Otherwise, 5643 is a composite number.
To explain better, if 5643 is only divisible by 1 and 5643, then it is a prime number, and if 5643 is divisible by more than 5643 and 1, then it is a composite number.
The factors of 5643 are as follows:
1, 3, 9, 11, 19, 27, 33, 57, 99, 171, 209, 297, 513, 627, 1881, 5643
Therefore, since 5643 is divisible by more than one and itself, the answer to the
question "Is 5643 prime or composite?" is highlighted in blue below.
