To determine if 260 is a prime number or a composite number, we simply look at the factors for 260.
If the factors of 260 are only 260 and 1, then we know that 260 is a prime number. Otherwise, 260 is a composite number.
To explain better, if 260 is only divisible by 1 and 260, then it is a prime number, and if 260 is divisible by more than 260 and 1, then it is a composite number.
The factors of 260 are as follows:
1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
Therefore, since 260 is divisible by more than one and itself, the answer to the
question "Is 260 prime or composite?" is highlighted in blue below.
composite
Is 261 prime or composite?
OK. Now you know that 260 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.
