To determine if 1836 is a prime number or a composite number, we simply look at the factors for 1836.
If the factors of 1836 are only 1836 and 1, then we know that 1836 is a prime number. Otherwise, 1836 is a composite number.
To explain better, if 1836 is only divisible by 1 and 1836, then it is a prime number, and if 1836 is divisible by more than 1836 and 1, then it is a composite number.
The factors of 1836 are as follows:
1, 2, 3, 4, 6, 9, 12, 17, 18, 27, 34, 36, 51, 54, 68, 102, 108, 153, 204, 306, 459, 612, 918, 1836
Therefore, since 1836 is divisible by more than one and itself, the answer to the
question "Is 1836 prime or composite?" is highlighted in blue below.
composite
Is 1837 prime or composite?
