To determine if 263 is a prime number or a composite number, we simply look at the factors for 263.
If the factors of 263 are only 263 and 1, then we know that 263 is a prime number. Otherwise, 263 is a composite number.
To explain better, if 263 is only divisible by 1 and 263, then it is a prime number, and if 263 is divisible by more than 263 and 1, then it is a composite number.
The factors of 263 are as follows:
1, 263
Therefore, since 263 is divisible by only one and itself, the answer to the
question "Is 263 prime or composite?" is highlighted in blue below.
prime
Is 264 prime or composite?
