To determine if 1631 is a prime number or a composite number, we simply look at the factors for 1631.
If the factors of 1631 are only 1631 and 1, then we know that 1631 is a prime number. Otherwise, 1631 is a composite number.
To explain better, if 1631 is only divisible by 1 and 1631, then it is a prime number, and if 1631 is divisible by more than 1631 and 1, then it is a composite number.
The factors of 1631 are as follows:
1, 7, 233, 1631
Therefore, since 1631 is divisible by more than one and itself, the answer to the
question "Is 1631 prime or composite?" is highlighted in blue below.
composite
Is 1632 prime or composite?
OK. Now you know that 1631 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.
