To determine if 3220 is a prime number or a composite number, we simply look at the factors for 3220.
If the factors of 3220 are only 3220 and 1, then we know that 3220 is a prime number. Otherwise, 3220 is a composite number.
To explain better, if 3220 is only divisible by 1 and 3220, then it is a prime number, and if 3220 is divisible by more than 3220 and 1, then it is a composite number.
The factors of 3220 are as follows:
1, 2, 4, 5, 7, 10, 14, 20, 23, 28, 35, 46, 70, 92, 115, 140, 161, 230, 322, 460, 644, 805, 1610, 3220
Therefore, since 3220 is divisible by more than one and itself, the answer to the
question "Is 3220 prime or composite?" is highlighted in blue below.
composite
Is 3221 prime or composite?
