To determine if 1026 is a prime number or a composite number, we simply look at the factors for 1026.
If the factors of 1026 are only 1026 and 1, then we know that 1026 is a prime number. Otherwise, 1026 is a composite number.
To explain better, if 1026 is only divisible by 1 and 1026, then it is a prime number, and if 1026 is divisible by more than 1026 and 1, then it is a composite number.
The factors of 1026 are as follows:
1, 2, 3, 6, 9, 18, 19, 27, 38, 54, 57, 114, 171, 342, 513, 1026
Therefore, since 1026 is divisible by more than one and itself, the answer to the
question "Is 1026 prime or composite?" is highlighted in blue below.
composite
Is 1027 prime or composite?
OK. Now you know that 1026 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.
