To determine if 1850 is a prime number or a composite number, we simply look at the factors for 1850.
If the factors of 1850 are only 1850 and 1, then we know that 1850 is a prime number. Otherwise, 1850 is a composite number.
To explain better, if 1850 is only divisible by 1 and 1850, then it is a prime number, and if 1850 is divisible by more than 1850 and 1, then it is a composite number.
The factors of 1850 are as follows:
1, 2, 5, 10, 25, 37, 50, 74, 185, 370, 925, 1850
Therefore, since 1850 is divisible by more than one and itself, the answer to the
question "Is 1850 prime or composite?" is highlighted in blue below.
composite
Is 1851 prime or composite?
