To determine if 9858 is a prime number or a composite number, we simply look at the factors for 9858.
If the factors of 9858 are only 9858 and 1, then we know that 9858 is a prime number. Otherwise, 9858 is a composite number.
To explain better, if 9858 is only divisible by 1 and 9858, then it is a prime number, and if 9858 is divisible by more than 9858 and 1, then it is a composite number.
The factors of 9858 are as follows:
1, 2, 3, 6, 31, 53, 62, 93, 106, 159, 186, 318, 1643, 3286, 4929, 9858
Therefore, since 9858 is divisible by more than one and itself, the answer to the
question "Is 9858 prime or composite?" is highlighted in blue below.
