To determine if 340 is a prime number or a composite number, we simply look at the factors for 340.
If the factors of 340 are only 340 and 1, then we know that 340 is a prime number. Otherwise, 340 is a composite number.
To explain better, if 340 is only divisible by 1 and 340, then it is a prime number, and if 340 is divisible by more than 340 and 1, then it is a composite number.
The factors of 340 are as follows:
1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
Therefore, since 340 is divisible by more than one and itself, the answer to the
question "Is 340 prime or composite?" is highlighted in blue below.
composite
Is 341 prime or composite?
OK. Now you know that 340 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.
