To determine if 1025 is a prime number or a composite number, we simply look at the factors for 1025.
If the factors of 1025 are only 1025 and 1, then we know that 1025 is a prime number. Otherwise, 1025 is a composite number.
To explain better, if 1025 is only divisible by 1 and 1025, then it is a prime number, and if 1025 is divisible by more than 1025 and 1, then it is a composite number.
The factors of 1025 are as follows:
1, 5, 25, 41, 205, 1025
Therefore, since 1025 is divisible by more than one and itself, the answer to the
question "Is 1025 prime or composite?" is highlighted in blue below.
composite
Is 1026 prime or composite?
OK. Now you know that 1025 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.
