To determine if 386 is a prime number or a composite number, we simply look at the factors for 386.
If the factors of 386 are only 386 and 1, then we know that 386 is a prime number. Otherwise, 386 is a composite number.
To explain better, if 386 is only divisible by 1 and 386, then it is a prime number, and if 386 is divisible by more than 386 and 1, then it is a composite number.
The factors of 386 are as follows:
1, 2, 193, 386
Therefore, since 386 is divisible by more than one and itself, the answer to the
question "Is 386 prime or composite?" is highlighted in blue below.
composite
Is 387 prime or composite?
OK. Now you know that 386 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.
