To determine if 211 is a prime or composite number, we need to check if it has factors other than 1 and itself. We can try dividing 211 by prime numbers up to its square root, which is approximately 14.5: 211 ÷ 2 = 105.5 (not a whole number) 211 ÷ 3 = 70.333... (not a whole number) 211 ÷ 5 = 42.2 (not a whole number) 211 ÷ 7 = 30.142... (not a whole number) 211 ÷ 11 = 19.181... (not a whole number) 211 ÷ 13 = 16.230... (not a whole number) As we can see, none of these divisions result in a whole number. So, 211 is not divisible by any prime number less than its square root. Therefore, 211 only has factors of 1 and itself, which means it is a prime number.
