To determine if 3861 is a prime number or a composite number, we simply look at the factors for 3861.
If the factors of 3861 are only 3861 and 1, then we know that 3861 is a prime number. Otherwise, 3861 is a composite number.
To explain better, if 3861 is only divisible by 1 and 3861, then it is a prime number, and if 3861 is divisible by more than 3861 and 1, then it is a composite number.
The factors of 3861 are as follows:
1, 3, 9, 11, 13, 27, 33, 39, 99, 117, 143, 297, 351, 429, 1287, 3861
Therefore, since 3861 is divisible by more than one and itself, the answer to the
question "Is 3861 prime or composite?" is highlighted in blue below.
composite
Is 3862 prime or composite?
