To determine if 1942 is a prime number or a composite number, we simply look at the factors for 1942.
If the factors of 1942 are only 1942 and 1, then we know that 1942 is a prime number. Otherwise, 1942 is a composite number.
To explain better, if 1942 is only divisible by 1 and 1942, then it is a prime number, and if 1942 is divisible by more than 1942 and 1, then it is a composite number.
The factors of 1942 are as follows:
