To determine if 1743 is a prime number or a composite number, we simply look at the factors for 1743.
If the factors of 1743 are only 1743 and 1, then we know that 1743 is a prime number. Otherwise, 1743 is a composite number.
To explain better, if 1743 is only divisible by 1 and 1743, then it is a prime number, and if 1743 is divisible by more than 1743 and 1, then it is a composite number.
The factors of 1743 are as follows:
1, 3, 7, 21, 83, 249, 581, 1743
Therefore, since 1743 is divisible by more than one and itself, the answer to the
question "Is 1743 prime or composite?" is highlighted in blue below.
