To determine if 5415 is a prime number or a composite number, we simply look at the factors for 5415.
If the factors of 5415 are only 5415 and 1, then we know that 5415 is a prime number. Otherwise, 5415 is a composite number.
To explain better, if 5415 is only divisible by 1 and 5415, then it is a prime number, and if 5415 is divisible by more than 5415 and 1, then it is a composite number.
The factors of 5415 are as follows:
1, 3, 5, 15, 19, 57, 95, 285, 361, 1083, 1805, 5415
Therefore, since 5415 is divisible by more than one and itself, the answer to the
question "Is 5415 prime or composite?" is highlighted in blue below.
composite
