To determine if 1098 is a prime number or a composite number, we simply look at the factors for 1098.
If the factors of 1098 are only 1098 and 1, then we know that 1098 is a prime number. Otherwise, 1098 is a composite number.
To explain better, if 1098 is only divisible by 1 and 1098, then it is a prime number, and if 1098 is divisible by more than 1098 and 1, then it is a composite number.
The factors of 1098 are as follows:
1, 2, 3, 6, 9, 18, 61, 122, 183, 366, 549, 1098
Therefore, since 1098 is divisible by more than one and itself, the answer to the
question "Is 1098 prime or composite?" is highlighted in blue below.
composite
