To determine if 1790 is a prime number or a composite number, we simply look at the factors for 1790.
If the factors of 1790 are only 1790 and 1, then we know that 1790 is a prime number. Otherwise, 1790 is a composite number.
To explain better, if 1790 is only divisible by 1 and 1790, then it is a prime number, and if 1790 is divisible by more than 1790 and 1, then it is a composite number.
The factors of 1790 are as follows:
1, 2, 5, 10, 179, 358, 895, 1790
Therefore, since 1790 is divisible by more than one and itself, the answer to the
question "Is 1790 prime or composite?" is highlighted in blue below.
