To determine if 1786 is a prime number or a composite number, we simply look at the factors for 1786.
If the factors of 1786 are only 1786 and 1, then we know that 1786 is a prime number. Otherwise, 1786 is a composite number.
To explain better, if 1786 is only divisible by 1 and 1786, then it is a prime number, and if 1786 is divisible by more than 1786 and 1, then it is a composite number.
The factors of 1786 are as follows:
1, 2, 19, 38, 47, 94, 893, 1786
Therefore, since 1786 is divisible by more than one and itself, the answer to the
question "Is 1786 prime or composite?" is highlighted in blue below.
