To determine if 2430 is a prime number or a composite number, we simply look at the factors for 2430.
If the factors of 2430 are only 2430 and 1, then we know that 2430 is a prime number. Otherwise, 2430 is a composite number.
To explain better, if 2430 is only divisible by 1 and 2430, then it is a prime number, and if 2430 is divisible by more than 2430 and 1, then it is a composite number.
The factors of 2430 are as follows:
1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 243, 270, 405, 486, 810, 1215, 2430
Therefore, since 2430 is divisible by more than one and itself, the answer to the
question "Is 2430 prime or composite?" is highlighted in blue below.
composite
