To determine if 5478 is a prime number or a composite number, we simply look at the factors for 5478.
If the factors of 5478 are only 5478 and 1, then we know that 5478 is a prime number. Otherwise, 5478 is a composite number.
To explain better, if 5478 is only divisible by 1 and 5478, then it is a prime number, and if 5478 is divisible by more than 5478 and 1, then it is a composite number.
The factors of 5478 are as follows:
1, 2, 3, 6, 11, 22, 33, 66, 83, 166, 249, 498, 913, 1826, 2739, 5478
Therefore, since 5478 is divisible by more than one and itself, the answer to the
question "Is 5478 prime or composite?" is highlighted in blue below.
