To determine if 1773 is a prime number or a composite number, we simply look at the factors for 1773.
If the factors of 1773 are only 1773 and 1, then we know that 1773 is a prime number. Otherwise, 1773 is a composite number.
To explain better, if 1773 is only divisible by 1 and 1773, then it is a prime number, and if 1773 is divisible by more than 1773 and 1, then it is a composite number.
The factors of 1773 are as follows:
1, 3, 9, 197, 591, 1773
Therefore, since 1773 is divisible by more than one and itself, the answer to the
question "Is 1773 prime or composite?" is highlighted in blue below.
