To determine if 1901 is a prime number or a composite number, we simply look at the factors for 1901.
If the factors of 1901 are only 1901 and 1, then we know that 1901 is a prime number. Otherwise, 1901 is a composite number.
To explain better, if 1901 is only divisible by 1 and 1901, then it is a prime number, and if 1901 is divisible by more than 1901 and 1, then it is a composite number.
The factors of 1901 are as follows:
1, 1901
Therefore, since 1901 is divisible by only one and itself, the answer to the
question "Is 1901 prime or composite?" is highlighted in blue below.
prime
Is 1902 prime or composite?
