To determine if 6990 is a prime number or a composite number, we simply look at the factors for 6990.
If the factors of 6990 are only 6990 and 1, then we know that 6990 is a prime number. Otherwise, 6990 is a composite number.
To explain better, if 6990 is only divisible by 1 and 6990, then it is a prime number, and if 6990 is divisible by more than 6990 and 1, then it is a composite number.
The factors of 6990 are as follows:
1, 2, 3, 5, 6, 10, 15, 30, 233, 466, 699, 1165, 1398, 2330, 3495, 6990
Therefore, since 6990 is divisible by more than one and itself, the answer to the
question "Is 6990 prime or composite?" is highlighted in blue below.
composite
Is 6991 prime or composite?
