To determine if 1827 is a prime number or a composite number, we simply look at the factors for 1827.
If the factors of 1827 are only 1827 and 1, then we know that 1827 is a prime number. Otherwise, 1827 is a composite number.
To explain better, if 1827 is only divisible by 1 and 1827, then it is a prime number, and if 1827 is divisible by more than 1827 and 1, then it is a composite number.
The factors of 1827 are as follows:
1, 3, 7, 9, 21, 29, 63, 87, 203, 261, 609, 1827
Therefore, since 1827 is divisible by more than one and itself, the answer to the
question "Is 1827 prime or composite?" is highlighted in blue below.
