To determine if 1807 is a prime number or a composite number, we simply look at the factors for 1807.
If the factors of 1807 are only 1807 and 1, then we know that 1807 is a prime number. Otherwise, 1807 is a composite number.
To explain better, if 1807 is only divisible by 1 and 1807, then it is a prime number, and if 1807 is divisible by more than 1807 and 1, then it is a composite number.
The factors of 1807 are as follows:
1, 13, 139, 1807
Therefore, since 1807 is divisible by more than one and itself, the answer to the
question "Is 1807 prime or composite?" is highlighted in blue below.
composite
Is 1808 prime or composite?
