To determine if 1705 is a prime number or a composite number, we simply look at the factors for 1705.
If the factors of 1705 are only 1705 and 1, then we know that 1705 is a prime number. Otherwise, 1705 is a composite number.
To explain better, if 1705 is only divisible by 1 and 1705, then it is a prime number, and if 1705 is divisible by more than 1705 and 1, then it is a composite number.
The factors of 1705 are as follows:
1, 5, 11, 31, 55, 155, 341, 1705
Therefore, since 1705 is divisible by more than one and itself, the answer to the
question "Is 1705 prime or composite?" is highlighted in blue below.
composite
Is 1706 prime or composite?
