To determine if 1727 is a prime number or a composite number, we simply look at the factors for 1727.
If the factors of 1727 are only 1727 and 1, then we know that 1727 is a prime number. Otherwise, 1727 is a composite number.
To explain better, if 1727 is only divisible by 1 and 1727, then it is a prime number, and if 1727 is divisible by more than 1727 and 1, then it is a composite number.
The factors of 1727 are as follows:
1, 11, 157, 1727
Therefore, since 1727 is divisible by more than one and itself, the answer to the
question "Is 1727 prime or composite?" is highlighted in blue below.
