To determine if 7665 is a prime number or a composite number, we simply look at the factors for 7665.
If the factors of 7665 are only 7665 and 1, then we know that 7665 is a prime number. Otherwise, 7665 is a composite number.
To explain better, if 7665 is only divisible by 1 and 7665, then it is a prime number, and if 7665 is divisible by more than 7665 and 1, then it is a composite number.
The factors of 7665 are as follows:
1, 3, 5, 7, 15, 21, 35, 73, 105, 219, 365, 511, 1095, 1533, 2555, 7665
Therefore, since 7665 is divisible by more than one and itself, the answer to the
question "Is 7665 prime or composite?" is highlighted in blue below.
