To determine if 1715 is a prime number or a composite number, we simply look at the factors for 1715.
If the factors of 1715 are only 1715 and 1, then we know that 1715 is a prime number. Otherwise, 1715 is a composite number.
To explain better, if 1715 is only divisible by 1 and 1715, then it is a prime number, and if 1715 is divisible by more than 1715 and 1, then it is a composite number.
The factors of 1715 are as follows:
1, 5, 7, 35, 49, 245, 343, 1715
Therefore, since 1715 is divisible by more than one and itself, the answer to the
question "Is 1715 prime or composite?" is highlighted in blue below.
composite
Is 1716 prime or composite?
