To determine if 2045 is a prime number or a composite number, we simply look at the factors for 2045.
If the factors of 2045 are only 2045 and 1, then we know that 2045 is a prime number. Otherwise, 2045 is a composite number.
To explain better, if 2045 is only divisible by 1 and 2045, then it is a prime number, and if 2045 is divisible by more than 2045 and 1, then it is a composite number.
The factors of 2045 are as follows:
1, 5, 409, 2045
Therefore, since 2045 is divisible by more than one and itself, the answer to the
question "Is 2045 prime or composite?" is highlighted in blue below.
composite
Is 2046 prime or composite?
