To determine if 1401 is a prime number or a composite number, we simply look at the factors for 1401.
If the factors of 1401 are only 1401 and 1, then we know that 1401 is a prime number. Otherwise, 1401 is a composite number.
To explain better, if 1401 is only divisible by 1 and 1401, then it is a prime number, and if 1401 is divisible by more than 1401 and 1, then it is a composite number.
The factors of 1401 are as follows:
1, 3, 467, 1401
Therefore, since 1401 is divisible by more than one and itself, the answer to the
question "Is 1401 prime or composite?" is highlighted in blue below.
composite
Is 1402 prime or composite?
OK. Now you know that 1401 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.
