To determine if 1875 is a prime number or a composite number, we simply look at the factors for 1875.
If the factors of 1875 are only 1875 and 1, then we know that 1875 is a prime number. Otherwise, 1875 is a composite number.
To explain better, if 1875 is only divisible by 1 and 1875, then it is a prime number, and if 1875 is divisible by more than 1875 and 1, then it is a composite number.
The factors of 1875 are as follows:
1, 3, 5, 15, 25, 75, 125, 375, 625, 1875
Therefore, since 1875 is divisible by more than one and itself, the answer to the
question "Is 1875 prime or composite?" is highlighted in blue below.
composite
