To determine if 9765 is a prime number or a composite number, we simply look at the factors for 9765.
If the factors of 9765 are only 9765 and 1, then we know that 9765 is a prime number. Otherwise, 9765 is a composite number.
To explain better, if 9765 is only divisible by 1 and 9765, then it is a prime number, and if 9765 is divisible by more than 9765 and 1, then it is a composite number.
The factors of 9765 are as follows:
1, 3, 5, 7, 9, 15, 21, 31, 35, 45, 63, 93, 105, 155, 217, 279, 315, 465, 651, 1085, 1395, 1953, 3255, 9765
Therefore, since 9765 is divisible by more than one and itself, the answer to the
question "Is 9765 prime or composite?" is highlighted in blue below.
