To determine if 240 is a prime number or a composite number, we simply look at the factors for 240.
If the factors of 240 are only 240 and 1, then we know that 240 is a prime number. Otherwise, 240 is a composite number.
To explain better, if 240 is only divisible by 1 and 240, then it is a prime number, and if 240 is divisible by more than 240 and 1, then it is a composite number.
The factors of 240 are as follows:
1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
Therefore, since 240 is divisible by more than one and itself, the answer to the
question "Is 240 prime or composite?" is highlighted in blue below.
composite
Is 241 prime or composite?
OK. Now you know that 240 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.
