To determine if 5355 is a prime number or a composite number, we simply look at the factors for 5355.
If the factors of 5355 are only 5355 and 1, then we know that 5355 is a prime number. Otherwise, 5355 is a composite number.
To explain better, if 5355 is only divisible by 1 and 5355, then it is a prime number, and if 5355 is divisible by more than 5355 and 1, then it is a composite number.
The factors of 5355 are as follows:
1, 3, 5, 7, 9, 15, 17, 21, 35, 45, 51, 63, 85, 105, 119, 153, 255, 315, 357, 595, 765, 1071, 1785, 5355
Therefore, since 5355 is divisible by more than one and itself, the answer to the
question "Is 5355 prime or composite?" is highlighted in blue below.
