To determine if 768 is a prime number or a composite number, we simply look at the factors for 768.
If the factors of 768 are only 768 and 1, then we know that 768 is a prime number. Otherwise, 768 is a composite number.
To explain better, if 768 is only divisible by 1 and 768, then it is a prime number, and if 768 is divisible by more than 768 and 1, then it is a composite number.
The factors of 768 are as follows:
1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
Therefore, since 768 is divisible by more than one and itself, the answer to the
question "Is 768 prime or composite?" is highlighted in blue below.
composite
Is 769 prime or composite?
OK. Now you know that 768 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.
