To determine if 764 is a prime number or a composite number, we simply look at the factors for 764.
If the factors of 764 are only 764 and 1, then we know that 764 is a prime number. Otherwise, 764 is a composite number.
To explain better, if 764 is only divisible by 1 and 764, then it is a prime number, and if 764 is divisible by more than 764 and 1, then it is a composite number.
The factors of 764 are as follows:
1, 2, 4, 191, 382, 764
Therefore, since 764 is divisible by more than one and itself, the answer to the
question "Is 764 prime or composite?" is highlighted in blue below.
composite
Is 765 prime or composite?
OK. Now you know that 764 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.
