To determine if 1731 is a prime number or a composite number, we simply look at the factors for 1731.
If the factors of 1731 are only 1731 and 1, then we know that 1731 is a prime number. Otherwise, 1731 is a composite number.
To explain better, if 1731 is only divisible by 1 and 1731, then it is a prime number, and if 1731 is divisible by more than 1731 and 1, then it is a composite number.
The factors of 1731 are as follows:
1, 3, 577, 1731
Therefore, since 1731 is divisible by more than one and itself, the answer to the
question "Is 1731 prime or composite?" is highlighted in blue below.
composite
Is 1732 prime or composite?
