To determine if 440 is a prime number or a composite number, we simply look at the factors for 440.
If the factors of 440 are only 440 and 1, then we know that 440 is a prime number. Otherwise, 440 is a composite number.
To explain better, if 440 is only divisible by 1 and 440, then it is a prime number, and if 440 is divisible by more than 440 and 1, then it is a composite number.
The factors of 440 are as follows:
1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
Therefore, since 440 is divisible by more than one and itself, the answer to the
question "Is 440 prime or composite?" is highlighted in blue below.
composite
Is 441 prime or composite?
OK. Now you know that 440 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
