To determine if 1408 is a prime number or a composite number, we simply look at the factors for 1408.
If the factors of 1408 are only 1408 and 1, then we know that 1408 is a prime number. Otherwise, 1408 is a composite number.
To explain better, if 1408 is only divisible by 1 and 1408, then it is a prime number, and if 1408 is divisible by more than 1408 and 1, then it is a composite number.
The factors of 1408 are as follows:
1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 128, 176, 352, 704, 1408
Therefore, since 1408 is divisible by more than one and itself, the answer to the
question "Is 1408 prime or composite?" is highlighted in blue below.
composite
Is 1409 prime or composite?
