To determine if 1984 is a prime number or a composite number, we simply look at the factors for 1984.
If the factors of 1984 are only 1984 and 1, then we know that 1984 is a prime number. Otherwise, 1984 is a composite number.
To explain better, if 1984 is only divisible by 1 and 1984, then it is a prime number, and if 1984 is divisible by more than 1984 and 1, then it is a composite number.
The factors of 1984 are as follows:
1, 2, 4, 8, 16, 31, 32, 62, 64, 124, 248, 496, 992, 1984
Therefore, since 1984 is divisible by more than one and itself, the answer to the
question "Is 1984 prime or composite?" is highlighted in blue below.
composite
Is 1985 prime or composite?
