To determine if 5642 is a prime number or a composite number, we simply look at the factors for 5642.
If the factors of 5642 are only 5642 and 1, then we know that 5642 is a prime number. Otherwise, 5642 is a composite number.
To explain better, if 5642 is only divisible by 1 and 5642, then it is a prime number, and if 5642 is divisible by more than 5642 and 1, then it is a composite number.
The factors of 5642 are as follows:
1, 2, 7, 13, 14, 26, 31, 62, 91, 182, 217, 403, 434, 806, 2821, 5642
Therefore, since 5642 is divisible by more than one and itself, the answer to the
question "Is 5642 prime or composite?" is highlighted in blue below.
