To determine if 3216 is a prime number or a composite number, we simply look at the factors for 3216.
If the factors of 3216 are only 3216 and 1, then we know that 3216 is a prime number. Otherwise, 3216 is a composite number.
To explain better, if 3216 is only divisible by 1 and 3216, then it is a prime number, and if 3216 is divisible by more than 3216 and 1, then it is a composite number.
The factors of 3216 are as follows:
1, 2, 3, 4, 6, 8, 12, 16, 24, 48, 67, 134, 201, 268, 402, 536, 804, 1072, 1608, 3216
Therefore, since 3216 is divisible by more than one and itself, the answer to the
question "Is 3216 prime or composite?" is highlighted in blue below.
composite
Is 3217 prime or composite?
