To determine if 2478 is a prime number or a composite number, we simply look at the factors for 2478.
If the factors of 2478 are only 2478 and 1, then we know that 2478 is a prime number. Otherwise, 2478 is a composite number.
To explain better, if 2478 is only divisible by 1 and 2478, then it is a prime number, and if 2478 is divisible by more than 2478 and 1, then it is a composite number.
The factors of 2478 are as follows:
1, 2, 3, 6, 7, 14, 21, 42, 59, 118, 177, 354, 413, 826, 1239, 2478
Therefore, since 2478 is divisible by more than one and itself, the answer to the
question "Is 2478 prime or composite?" is highlighted in blue below.
