To determine if 1485 is a prime number or a composite number, we simply look at the factors for 1485.
If the factors of 1485 are only 1485 and 1, then we know that 1485 is a prime number. Otherwise, 1485 is a composite number.
To explain better, if 1485 is only divisible by 1 and 1485, then it is a prime number, and if 1485 is divisible by more than 1485 and 1, then it is a composite number.
The factors of 1485 are as follows:
1, 3, 5, 9, 11, 15, 27, 33, 45, 55, 99, 135, 165, 297, 495, 1485
Therefore, since 1485 is divisible by more than one and itself, the answer to the
question "Is 1485 prime or composite?" is highlighted in blue below.
composite
Is 1486 prime or composite?
