To determine if 3154 is a prime number or a composite number, we simply look at the factors for 3154.
If the factors of 3154 are only 3154 and 1, then we know that 3154 is a prime number. Otherwise, 3154 is a composite number.
To explain better, if 3154 is only divisible by 1 and 3154, then it is a prime number, and if 3154 is divisible by more than 3154 and 1, then it is a composite number.
The factors of 3154 are as follows:
1, 2, 19, 38, 83, 166, 1577, 3154
Therefore, since 3154 is divisible by more than one and itself, the answer to the
