To determine if 1802 is a prime number or a composite number, we simply look at the factors for 1802.
If the factors of 1802 are only 1802 and 1, then we know that 1802 is a prime number. Otherwise, 1802 is a composite number.
To explain better, if 1802 is only divisible by 1 and 1802, then it is a prime number, and if 1802 is divisible by more than 1802 and 1, then it is a composite number.
The factors of 1802 are as follows:
1, 2, 17, 34, 53, 106, 901, 1802
Therefore, since 1802 is divisible by more than one and itself, the answer to the
question "Is 1802 prime or composite?" is highlighted in blue below.
composite
Is 1803 prime or composite?
