To determine if 5445 is a prime number or a composite number, we simply look at the factors for 5445.
If the factors of 5445 are only 5445 and 1, then we know that 5445 is a prime number. Otherwise, 5445 is a composite number.
To explain better, if 5445 is only divisible by 1 and 5445, then it is a prime number, and if 5445 is divisible by more than 5445 and 1, then it is a composite number.
The factors of 5445 are as follows:
1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 121, 165, 363, 495, 605, 1089, 1815, 5445
Therefore, since 5445 is divisible by more than one and itself, the answer to the
question "Is 5445 prime or composite?" is highlighted in blue below.
