To determine if 1826 is a prime number or a composite number, we simply look at the factors for 1826.
If the factors of 1826 are only 1826 and 1, then we know that 1826 is a prime number. Otherwise, 1826 is a composite number.
To explain better, if 1826 is only divisible by 1 and 1826, then it is a prime number, and if 1826 is divisible by more than 1826 and 1, then it is a composite number.
The factors of 1826 are as follows:
1, 2, 11, 22, 83, 166, 913, 1826
Therefore, since 1826 is divisible by more than one and itself, the answer to the
question "Is 1826 prime or composite?" is highlighted in blue below.
