To determine if 2742 is a prime number or a composite number, we simply look at the factors for 2742.
If the factors of 2742 are only 2742 and 1, then we know that 2742 is a prime number. Otherwise, 2742 is a composite number.
To explain better, if 2742 is only divisible by 1 and 2742, then it is a prime number, and if 2742 is divisible by more than 2742 and 1, then it is a composite number.
The factors of 2742 are as follows:
1, 2, 3, 6, 457, 914, 1371, 2742
