To determine if 445 is a prime number or a composite number, we simply look at the factors for 445.
If the factors of 445 are only 445 and 1, then we know that 445 is a prime number. Otherwise, 445 is a composite number.
To explain better, if 445 is only divisible by 1 and 445, then it is a prime number, and if 445 is divisible by more than 445 and 1, then it is a composite number.
The factors of 445 are as follows:
1, 5, 89, 445
Therefore, since 445 is divisible by more than one and itself, the answer to the
question "Is 445 prime or composite?" is highlighted in blue below.
composite
Is 446 prime or composite?
