To determine if 3894 is a prime number or a composite number, we simply look at the factors for 3894.
If the factors of 3894 are only 3894 and 1, then we know that 3894 is a prime number. Otherwise, 3894 is a composite number.
To explain better, if 3894 is only divisible by 1 and 3894, then it is a prime number, and if 3894 is divisible by more than 3894 and 1, then it is a composite number.
The factors of 3894 are as follows:
1, 2, 3, 6, 11, 22, 33, 59, 66, 118, 177, 354, 649, 1298, 1947, 3894
Therefore, since 3894 is divisible by more than one and itself, the answer to the
question "Is 3894 prime or composite?" is highlighted in blue below.
