To determine if 2900 is a prime number or a composite number, we simply look at the factors for 2900.
If the factors of 2900 are only 2900 and 1, then we know that 2900 is a prime number. Otherwise, 2900 is a composite number.
To explain better, if 2900 is only divisible by 1 and 2900, then it is a prime number, and if 2900 is divisible by more than 2900 and 1, then it is a composite number.
The factors of 2900 are as follows:
1, 2, 4, 5, 10, 20, 25, 29, 50, 58, 100, 116, 145, 290, 580, 725, 1450, 2900
Therefore, since 2900 is divisible by more than one and itself, the answer to the
question "Is 2900 prime or composite?" is highlighted in blue below.
composite
Is 2901 prime or composite?
OK. Now you know that 2900 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.
