To determine if 448 is a prime number or a composite number, we simply look at the factors for 448.
If the factors of 448 are only 448 and 1, then we know that 448 is a prime number. Otherwise, 448 is a composite number.
To explain better, if 448 is only divisible by 1 and 448, then it is a prime number, and if 448 is divisible by more than 448 and 1, then it is a composite number.
The factors of 448 are as follows:
1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
Therefore, since 448 is divisible by more than one and itself, the answer to the
question "Is 448 prime or composite?" is highlighted in blue below.
composite
Is 449 prime or composite?
