To determine if 6858 is a prime number or a composite number, we simply look at the factors for 6858.
If the factors of 6858 are only 6858 and 1, then we know that 6858 is a prime number. Otherwise, 6858 is a composite number.
To explain better, if 6858 is only divisible by 1 and 6858, then it is a prime number, and if 6858 is divisible by more than 6858 and 1, then it is a composite number.
The factors of 6858 are as follows:
1, 2, 3, 6, 9, 18, 27, 54, 127, 254, 381, 762, 1143, 2286, 3429, 6858
Therefore, since 6858 is divisible by more than one and itself, the answer to the
question "Is 6858 prime or composite?" is highlighted in blue below.
