To determine if 1719 is a prime number or a composite number, we simply look at the factors for 1719.
If the factors of 1719 are only 1719 and 1, then we know that 1719 is a prime number. Otherwise, 1719 is a composite number.
To explain better, if 1719 is only divisible by 1 and 1719, then it is a prime number, and if 1719 is divisible by more than 1719 and 1, then it is a composite number.
The factors of 1719 are as follows:
1, 3, 9, 191, 573, 1719
Therefore, since 1719 is divisible by more than one and itself, the answer to the
question "Is 1719 prime or composite?" is highlighted in blue below.
composite
