To determine if 1216 is a prime number or a composite number, we simply look at the factors for 1216.
If the factors of 1216 are only 1216 and 1, then we know that 1216 is a prime number. Otherwise, 1216 is a composite number.
To explain better, if 1216 is only divisible by 1 and 1216, then it is a prime number, and if 1216 is divisible by more than 1216 and 1, then it is a composite number.
The factors of 1216 are as follows:
1, 2, 4, 8, 16, 19, 32, 38, 64, 76, 152, 304, 608, 1216
Therefore, since 1216 is divisible by more than one and itself, the answer to the
question "Is 1216 prime or composite?" is highlighted in blue below.
composite
Is 1217 prime or composite?
OK. Now you know that 1216 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.
