To determine if 3942 is a prime number or a composite number, we simply look at the factors for 3942.
If the factors of 3942 are only 3942 and 1, then we know that 3942 is a prime number. Otherwise, 3942 is a composite number.
To explain better, if 3942 is only divisible by 1 and 3942, then it is a prime number, and if 3942 is divisible by more than 3942 and 1, then it is a composite number.
The factors of 3942 are as follows:
1, 2, 3, 6, 9, 18, 27, 54, 73, 146, 219, 438, 657, 1314, 1971, 3942
Therefore, since 3942 is divisible by more than one and itself, the answer to the
question "Is 3942 prime or composite?" is highlighted in blue below.
