To determine if 5721 is a prime number or a composite number, we simply look at the factors for 5721.
If the factors of 5721 are only 5721 and 1, then we know that 5721 is a prime number. Otherwise, 5721 is a composite number.
To explain better, if 5721 is only divisible by 1 and 5721, then it is a prime number, and if 5721 is divisible by more than 5721 and 1, then it is a composite number.
The factors of 5721 are as follows:
1, 3, 1907, 5721
Therefore, since 5721 is divisible by more than one and itself, the answer to the
question "Is 5721 prime or composite?" is highlighted in blue below.
