To determine if 6780 is a prime number or a composite number, we simply look at the factors for 6780.
If the factors of 6780 are only 6780 and 1, then we know that 6780 is a prime number. Otherwise, 6780 is a composite number.
To explain better, if 6780 is only divisible by 1 and 6780, then it is a prime number, and if 6780 is divisible by more than 6780 and 1, then it is a composite number.
The factors of 6780 are as follows:
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60, 113, 226, 339, 452, 565, 678, 1130, 1356, 1695, 2260, 3390, 6780
Therefore, since 6780 is divisible by more than one and itself, the answer to the
question "Is 6780 prime or composite?" is highlighted in blue below.
composite
Is 6781 prime or composite?
