To determine if 1994 is a prime number or a composite number, we simply look at the factors for 1994.
If the factors of 1994 are only 1994 and 1, then we know that 1994 is a prime number. Otherwise, 1994 is a composite number.
To explain better, if 1994 is only divisible by 1 and 1994, then it is a prime number, and if 1994 is divisible by more than 1994 and 1, then it is a composite number.
The factors of 1994 are as follows:
1, 2, 997, 1994
Therefore, since 1994 is divisible by more than one and itself, the answer to the
question "Is 1994 prime or composite?" is highlighted in blue below.
