To determine if 2530 is a prime number or a composite number, we simply look at the factors for 2530.
If the factors of 2530 are only 2530 and 1, then we know that 2530 is a prime number. Otherwise, 2530 is a composite number.
To explain better, if 2530 is only divisible by 1 and 2530, then it is a prime number, and if 2530 is divisible by more than 2530 and 1, then it is a composite number.
The factors of 2530 are as follows:
1, 2, 5, 10, 11, 22, 23, 46, 55, 110, 115, 230, 253, 506, 1265, 2530
Therefore, since 2530 is divisible by more than one and itself, the answer to the
question "Is 2530 prime or composite?" is highlighted in blue below.
composite
Is 2531 prime or composite?
OK. Now you know that 2530 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.
