To determine if 2025 is a prime number or a composite number, we simply look at the factors for 2025.
If the factors of 2025 are only 2025 and 1, then we know that 2025 is a prime number. Otherwise, 2025 is a composite number.
To explain better, if 2025 is only divisible by 1 and 2025, then it is a prime number, and if 2025 is divisible by more than 2025 and 1, then it is a composite number.
The factors of 2025 are as follows:
1, 3, 5, 9, 15, 25, 27, 45, 75, 81, 135, 225, 405, 675, 2025
Therefore, since 2025 is divisible by more than one and itself, the answer to the
question "Is 2025 prime or composite?" is highlighted in blue below.
composite
Is 2026 prime or composite?
OK. Now you know that 2025 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.
