To determine if 785 is a prime number or a composite number, we simply look at the factors for 785.
If the factors of 785 are only 785 and 1, then we know that 785 is a prime number. Otherwise, 785 is a composite number.
To explain better, if 785 is only divisible by 1 and 785, then it is a prime number, and if 785 is divisible by more than 785 and 1, then it is a composite number.
The factors of 785 are as follows:
1, 5, 157, 785
Therefore, since 785 is divisible by more than one and itself, the answer to the
question "Is 785 prime or composite?" is highlighted in blue below.
composite
Is 786 prime or composite?
