To determine if 1968 is a prime number or a composite number, we simply look at the factors for 1968.
If the factors of 1968 are only 1968 and 1, then we know that 1968 is a prime number. Otherwise, 1968 is a composite number.
To explain better, if 1968 is only divisible by 1 and 1968, then it is a prime number, and if 1968 is divisible by more than 1968 and 1, then it is a composite number.
The factors of 1968 are as follows:
1, 2, 3, 4, 6, 8, 12, 16, 24, 41, 48, 82, 123, 164, 246, 328, 492, 656, 984, 1968
Therefore, since 1968 is divisible by more than one and itself, the answer to the
question "Is 1968 prime or composite?" is highlighted in blue below.
composite
Is 1969 prime or composite?
