To determine if 1992 is a prime number or a composite number, we simply look at the factors for 1992.
If the factors of 1992 are only 1992 and 1, then we know that 1992 is a prime number. Otherwise, 1992 is a composite number.
To explain better, if 1992 is only divisible by 1 and 1992, then it is a prime number, and if 1992 is divisible by more than 1992 and 1, then it is a composite number.
The factors of 1992 are as follows:
1, 2, 3, 4, 6, 8, 12, 24, 83, 166, 249, 332, 498, 664, 996, 1992
Therefore, since 1992 is divisible by more than one and itself, the answer to the
question "Is 1992 prime or composite?" is highlighted in blue below.
composite
Is 1993 prime or composite?
