To determine if 1099 is a prime number or a composite number, we simply look at the factors for 1099.
If the factors of 1099 are only 1099 and 1, then we know that 1099 is a prime number. Otherwise, 1099 is a composite number.
To explain better, if 1099 is only divisible by 1 and 1099, then it is a prime number, and if 1099 is divisible by more than 1099 and 1, then it is a composite number.
The factors of 1099 are as follows:
1, 7, 157, 1099
Therefore, since 1099 is divisible by more than one and itself, the answer to the
question "Is 1099 prime or composite?" is highlighted in blue below.
composite
Is 1100 prime or composite?
