To determine if 2500 is a prime number or a composite number, we simply look at the factors for 2500.
If the factors of 2500 are only 2500 and 1, then we know that 2500 is a prime number. Otherwise, 2500 is a composite number.
To explain better, if 2500 is only divisible by 1 and 2500, then it is a prime number, and if 2500 is divisible by more than 2500 and 1, then it is a composite number.
The factors of 2500 are as follows:
1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500, 625, 1250, 2500
Therefore, since 2500 is divisible by more than one and itself, the answer to the
question "Is 2500 prime or composite?" is highlighted in blue below.
composite
Is 2501 prime or composite?
OK. Now you know that 2500 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.
