To determine if 778 is a prime number or a composite number, we simply look at the factors for 778.
If the factors of 778 are only 778 and 1, then we know that 778 is a prime number. Otherwise, 778 is a composite number.
To explain better, if 778 is only divisible by 1 and 778, then it is a prime number, and if 778 is divisible by more than 778 and 1, then it is a composite number.
The factors of 778 are as follows:
1, 2, 389, 778
Therefore, since 778 is divisible by more than one and itself, the answer to the
question "Is 778 prime or composite?" is highlighted in blue below.
composite
Is 779 prime or composite?
