To determine if 1854 is a prime number or a composite number, we simply look at the factors for 1854.
If the factors of 1854 are only 1854 and 1, then we know that 1854 is a prime number. Otherwise, 1854 is a composite number.
To explain better, if 1854 is only divisible by 1 and 1854, then it is a prime number, and if 1854 is divisible by more than 1854 and 1, then it is a composite number.
The factors of 1854 are as follows:
1, 2, 3, 6, 9, 18, 103, 206, 309, 618, 927, 1854
Therefore, since 1854 is divisible by more than one and itself, the answer to the
question "Is 1854 prime or composite?" is highlighted in blue below.
composite
