To determine if 1568 is a prime number or a composite number, we simply look at the factors for 1568.
If the factors of 1568 are only 1568 and 1, then we know that 1568 is a prime number. Otherwise, 1568 is a composite number.
To explain better, if 1568 is only divisible by 1 and 1568, then it is a prime number, and if 1568 is divisible by more than 1568 and 1, then it is a composite number.
The factors of 1568 are as follows:
1, 2, 4, 7, 8, 14, 16, 28, 32, 49, 56, 98, 112, 196, 224, 392, 784, 1568
Therefore, since 1568 is divisible by more than one and itself, the answer to the
question "Is 1568 prime or composite?" is highlighted in blue below.
composite
Is 1569 prime or composite?
