To determine if 356 is a prime number or a composite number, we simply look at the factors for 356.
If the factors of 356 are only 356 and 1, then we know that 356 is a prime number. Otherwise, 356 is a composite number.
To explain better, if 356 is only divisible by 1 and 356, then it is a prime number, and if 356 is divisible by more than 356 and 1, then it is a composite number.
The factors of 356 are as follows:
1, 2, 4, 89, 178, 356
Therefore, since 356 is divisible by more than one and itself, the answer to the
question "Is 356 prime or composite?" is highlighted in blue below.
composite
Is 357 prime or composite?
OK. Now you know that 356 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.
