To determine if 9842 is a prime number or a composite number, we simply look at the factors for 9842.
If the factors of 9842 are only 9842 and 1, then we know that 9842 is a prime number. Otherwise, 9842 is a composite number.
To explain better, if 9842 is only divisible by 1 and 9842, then it is a prime number, and if 9842 is divisible by more than 9842 and 1, then it is a composite number.
The factors of 9842 are as follows:
1, 2, 7, 14, 19, 37, 38, 74, 133, 259, 266, 518, 703, 1406, 4921, 9842
Therefore, since 9842 is divisible by more than one and itself, the answer to the
question "Is 9842 prime or composite?" is highlighted in blue below.
