To determine if 3122 is a prime number or a composite number, we simply look at the factors for 3122.
If the factors of 3122 are only 3122 and 1, then we know that 3122 is a prime number. Otherwise, 3122 is a composite number.
To explain better, if 3122 is only divisible by 1 and 3122, then it is a prime number, and if 3122 is divisible by more than 3122 and 1, then it is a composite number.
The factors of 3122 are as follows:
1, 2, 7, 14, 223, 446, 1561, 3122
Therefore, since 3122 is divisible by more than one and itself, the answer to the
question "Is 3122 prime or composite?" is highlighted in blue below.
