To determine if 2028 is a prime number or a composite number, we simply look at the factors for 2028.
If the factors of 2028 are only 2028 and 1, then we know that 2028 is a prime number. Otherwise, 2028 is a composite number.
To explain better, if 2028 is only divisible by 1 and 2028, then it is a prime number, and if 2028 is divisible by more than 2028 and 1, then it is a composite number.
The factors of 2028 are as follows:
1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156, 169, 338, 507, 676, 1014, 2028
Therefore, since 2028 is divisible by more than one and itself, the answer to the
question "Is 2028 prime or composite?" is highlighted in blue below.
composite
Is 2029 prime or composite?
OK. Now you know that 2028 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
