To determine if 1902 is a prime number or a composite number, we simply look at the factors for 1902.
If the factors of 1902 are only 1902 and 1, then we know that 1902 is a prime number. Otherwise, 1902 is a composite number.
To explain better, if 1902 is only divisible by 1 and 1902, then it is a prime number, and if 1902 is divisible by more than 1902 and 1, then it is a composite number.
The factors of 1902 are as follows:
1, 2, 3, 6, 317, 634, 951, 1902
Therefore, since 1902 is divisible by more than one and itself, the answer to the
question "Is 1902 prime or composite?" is highlighted in blue below.
composite
Is 1903 prime or composite?
