To determine if 6825 is a prime number or a composite number, we simply look at the factors for 6825.
If the factors of 6825 are only 6825 and 1, then we know that 6825 is a prime number. Otherwise, 6825 is a composite number.
To explain better, if 6825 is only divisible by 1 and 6825, then it is a prime number, and if 6825 is divisible by more than 6825 and 1, then it is a composite number.
The factors of 6825 are as follows:
1, 3, 5, 7, 13, 15, 21, 25, 35, 39, 65, 75, 91, 105, 175, 195, 273, 325, 455, 525, 975, 1365, 2275, 6825
Therefore, since 6825 is divisible by more than one and itself, the answer to the
question "Is 6825 prime or composite?" is highlighted in blue below.
