To determine if 1782 is a prime number or a composite number, we simply look at the factors for 1782.
If the factors of 1782 are only 1782 and 1, then we know that 1782 is a prime number. Otherwise, 1782 is a composite number.
To explain better, if 1782 is only divisible by 1 and 1782, then it is a prime number, and if 1782 is divisible by more than 1782 and 1, then it is a composite number.
The factors of 1782 are as follows:
1, 2, 3, 6, 9, 11, 18, 22, 27, 33, 54, 66, 81, 99, 162, 198, 297, 594, 891, 1782
Therefore, since 1782 is divisible by more than one and itself, the answer to the
question "Is 1782 prime or composite?" is highlighted in blue below.
composite
Is 1783 prime or composite?
