To determine if 4025 is a prime number or a composite number, we simply look at the factors for 4025.
If the factors of 4025 are only 4025 and 1, then we know that 4025 is a prime number. Otherwise, 4025 is a composite number.
To explain better, if 4025 is only divisible by 1 and 4025, then it is a prime number, and if 4025 is divisible by more than 4025 and 1, then it is a composite number.
The factors of 4025 are as follows:
1, 5, 7, 23, 25, 35, 115, 161, 175, 575, 805, 4025
Therefore, since 4025 is divisible by more than one and itself, the answer to the
question "Is 4025 prime or composite?" is highlighted in blue below.
composite
Is 4026 prime or composite?
