To determine if 782 is a prime number or a composite number, we simply look at the factors for 782.
If the factors of 782 are only 782 and 1, then we know that 782 is a prime number. Otherwise, 782 is a composite number.
To explain better, if 782 is only divisible by 1 and 782, then it is a prime number, and if 782 is divisible by more than 782 and 1, then it is a composite number.
The factors of 782 are as follows:
1, 2, 17, 23, 34, 46, 391, 782
Therefore, since 782 is divisible by more than one and itself, the answer to the
question "Is 782 prime or composite?" is highlighted in blue below.
composite
Is 783 prime or composite?
