To determine if 4785 is a prime number or a composite number, we simply look at the factors for 4785.
If the factors of 4785 are only 4785 and 1, then we know that 4785 is a prime number. Otherwise, 4785 is a composite number.
To explain better, if 4785 is only divisible by 1 and 4785, then it is a prime number, and if 4785 is divisible by more than 4785 and 1, then it is a composite number.
The factors of 4785 are as follows:
1, 3, 5, 11, 15, 29, 33, 55, 87, 145, 165, 319, 435, 957, 1595, 4785
Therefore, since 4785 is divisible by more than one and itself, the answer to the
question "Is 4785 prime or composite?" is highlighted in blue below.
