To determine if 1765 is a prime number or a composite number, we simply look at the factors for 1765.
If the factors of 1765 are only 1765 and 1, then we know that 1765 is a prime number. Otherwise, 1765 is a composite number.
To explain better, if 1765 is only divisible by 1 and 1765, then it is a prime number, and if 1765 is divisible by more than 1765 and 1, then it is a composite number.
The factors of 1765 are as follows:
1, 5, 353, 1765
Therefore, since 1765 is divisible by more than one and itself, the answer to the
question "Is 1765 prime or composite?" is highlighted in blue below.
composite
