To determine if 7755 is a prime number or a composite number, we simply look at the factors for 7755.
If the factors of 7755 are only 7755 and 1, then we know that 7755 is a prime number. Otherwise, 7755 is a composite number.
To explain better, if 7755 is only divisible by 1 and 7755, then it is a prime number, and if 7755 is divisible by more than 7755 and 1, then it is a composite number.
The factors of 7755 are as follows:
1, 3, 5, 11, 15, 33, 47, 55, 141, 165, 235, 517, 705, 1551, 2585, 7755
Therefore, since 7755 is divisible by more than one and itself, the answer to the
question "Is 7755 prime or composite?" is highlighted in blue below.
