To determine if 9000 is a prime number or a composite number, we simply look at the factors for 9000.
If the factors of 9000 are only 9000 and 1, then we know that 9000 is a prime number. Otherwise, 9000 is a composite number.
To explain better, if 9000 is only divisible by 1 and 9000, then it is a prime number, and if 9000 is divisible by more than 9000 and 1, then it is a composite number.
The factors of 9000 are as follows:
1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 25, 30, 36, 40, 45, 50, 60, 72, 75, 90, 100, 120, 125, 150, 180, 200, 225, 250, 300, 360, 375, 450, 500, 600, 750, 900, 1000, 1125, 1500, 1800, 2250, 3000, 4500, 9000
Therefore, since 9000 is divisible by more than one and itself, the answer to the
question "Is 9000 prime or composite?" is highlighted in blue below.
composite
Is 9001 prime or composite?
OK. Now you know that 9000 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.
