To determine if 600 is a prime number or a composite number, we simply look at the factors for 600.
If the factors of 600 are only 600 and 1, then we know that 600 is a prime number. Otherwise, 600 is a composite number.
To explain better, if 600 is only divisible by 1 and 600, then it is a prime number, and if 600 is divisible by more than 600 and 1, then it is a composite number.
The factors of 600 are as follows:
1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
Therefore, since 600 is divisible by more than one and itself, the answer to the
question "Is 600 prime or composite?" is highlighted in blue below.
composite
Is 601 prime or composite?
OK. Now you know that 600 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.
