To determine if 3968 is a prime number or a composite number, we simply look at the factors for 3968.
If the factors of 3968 are only 3968 and 1, then we know that 3968 is a prime number. Otherwise, 3968 is a composite number.
To explain better, if 3968 is only divisible by 1 and 3968, then it is a prime number, and if 3968 is divisible by more than 3968 and 1, then it is a composite number.
The factors of 3968 are as follows:
1, 2, 4, 8, 16, 31, 32, 62, 64, 124, 128, 248, 496, 992, 1984, 3968
Therefore, since 3968 is divisible by more than one and itself, the answer to the
question "Is 3968 prime or composite?" is highlighted in blue below.
