To determine if 3146 is a prime number or a composite number, we simply look at the factors for 3146.
If the factors of 3146 are only 3146 and 1, then we know that 3146 is a prime number. Otherwise, 3146 is a composite number.
To explain better, if 3146 is only divisible by 1 and 3146, then it is a prime number, and if 3146 is divisible by more than 3146 and 1, then it is a composite number.
The factors of 3146 are as follows:
1, 2, 11, 13, 22, 26, 121, 143, 242, 286, 1573, 3146
Therefore, since 3146 is divisible by more than one and itself, the answer to the
question "Is 3146 prime or composite?" is highlighted in blue below.
