To determine if 3874 is a prime number or a composite number, we simply look at the factors for 3874.
If the factors of 3874 are only 3874 and 1, then we know that 3874 is a prime number. Otherwise, 3874 is a composite number.
To explain better, if 3874 is only divisible by 1 and 3874, then it is a prime number, and if 3874 is divisible by more than 3874 and 1, then it is a composite number.
The factors of 3874 are as follows:
