To determine if 3200 is a prime number or a composite number, we simply look at the factors for 3200.
If the factors of 3200 are only 3200 and 1, then we know that 3200 is a prime number. Otherwise, 3200 is a composite number.
To explain better, if 3200 is only divisible by 1 and 3200, then it is a prime number, and if 3200 is divisible by more than 3200 and 1, then it is a composite number.
The factors of 3200 are as follows:
1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 64, 80, 100, 128, 160, 200, 320, 400, 640, 800, 1600, 3200
Therefore, since 3200 is divisible by more than one and itself, the answer to the
question "Is 3200 prime or composite?" is highlighted in blue below.
composite
Is 3201 prime or composite?
