To determine if 8781 is a prime number or a composite number, we simply look at the factors for 8781.
If the factors of 8781 are only 8781 and 1, then we know that 8781 is a prime number. Otherwise, 8781 is a composite number.
To explain better, if 8781 is only divisible by 1 and 8781, then it is a prime number, and if 8781 is divisible by more than 8781 and 1, then it is a composite number.
The factors of 8781 are as follows:
1, 3, 2927, 8781
Therefore, since 8781 is divisible by more than one and itself, the answer to the
question "Is 8781 prime or composite?" is highlighted in blue below.
