To determine if 774 is a prime number or a composite number, we simply look at the factors for 774.
If the factors of 774 are only 774 and 1, then we know that 774 is a prime number. Otherwise, 774 is a composite number.
To explain better, if 774 is only divisible by 1 and 774, then it is a prime number, and if 774 is divisible by more than 774 and 1, then it is a composite number.
The factors of 774 are as follows:
1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
Therefore, since 774 is divisible by more than one and itself, the answer to the
question "Is 774 prime or composite?" is highlighted in blue below.
composite
Is 775 prime or composite?
