To determine if 3800 is a prime number or a composite number, we simply look at the factors for 3800.
If the factors of 3800 are only 3800 and 1, then we know that 3800 is a prime number. Otherwise, 3800 is a composite number.
To explain better, if 3800 is only divisible by 1 and 3800, then it is a prime number, and if 3800 is divisible by more than 3800 and 1, then it is a composite number.
The factors of 3800 are as follows:
1, 2, 4, 5, 8, 10, 19, 20, 25, 38, 40, 50, 76, 95, 100, 152, 190, 200, 380, 475, 760, 950, 1900, 3800
Therefore, since 3800 is divisible by more than one and itself, the answer to the
question "Is 3800 prime or composite?" is highlighted in blue below.
composite
Is 3801 prime or composite?
