To determine if 211 is a prime number or a composite number, we simply look at the factors for 211.
If the factors of 211 are only 211 and 1, then we know that 211 is a prime number. Otherwise, 211 is a composite number.
To explain better, if 211 is only divisible by 1 and 211, then it is a prime number, and if 211 is divisible by more than 211 and 1, then it is a composite number.
The factors of 211 are as follows:
1, 211
Therefore, since 211 is divisible by only one and itself, the answer to the
question "Is 211 prime or composite?" is highlighted in blue below.
prime
Is 212 prime or composite?
OK. Now you know that 211 is a prime 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.
