To determine if 8625 is a prime number or a composite number, we simply look at the factors for 8625.
If the factors of 8625 are only 8625 and 1, then we know that 8625 is a prime number. Otherwise, 8625 is a composite number.
To explain better, if 8625 is only divisible by 1 and 8625, then it is a prime number, and if 8625 is divisible by more than 8625 and 1, then it is a composite number.
The factors of 8625 are as follows:
1, 3, 5, 15, 23, 25, 69, 75, 115, 125, 345, 375, 575, 1725, 2875, 8625
Therefore, since 8625 is divisible by more than one and itself, the answer to the
question "Is 8625 prime or composite?" is highlighted in blue below.
