To determine if 4780 is a prime number or a composite number, we simply look at the factors for 4780.
If the factors of 4780 are only 4780 and 1, then we know that 4780 is a prime number. Otherwise, 4780 is a composite number.
To explain better, if 4780 is only divisible by 1 and 4780, then it is a prime number, and if 4780 is divisible by more than 4780 and 1, then it is a composite number.
The factors of 4780 are as follows:
1, 2, 4, 5, 10, 20, 239, 478, 956, 1195, 2390, 4780
Therefore, since 4780 is divisible by more than one and itself, the answer to the
question "Is 4780 prime or composite?" is highlighted in blue below.
composite
Is 4781 prime or composite?
