To determine if 920 is a prime number or a composite number, we simply look at the factors for 920.
If the factors of 920 are only 920 and 1, then we know that 920 is a prime number. Otherwise, 920 is a composite number.
To explain better, if 920 is only divisible by 1 and 920, then it is a prime number, and if 920 is divisible by more than 920 and 1, then it is a composite number.
The factors of 920 are as follows:
1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
Therefore, since 920 is divisible by more than one and itself, the answer to the
question "Is 920 prime or composite?" is highlighted in blue below.
composite
Is 921 prime or composite?
OK. Now you know that 920 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.
