To determine if 1375 is a prime number or a composite number, we simply look at the factors for 1375.
If the factors of 1375 are only 1375 and 1, then we know that 1375 is a prime number. Otherwise, 1375 is a composite number.
To explain better, if 1375 is only divisible by 1 and 1375, then it is a prime number, and if 1375 is divisible by more than 1375 and 1, then it is a composite number.
The factors of 1375 are as follows:
1, 5, 11, 25, 55, 125, 275, 1375
Therefore, since 1375 is divisible by more than one and itself, the answer to the
question "Is 1375 prime or composite?" is highlighted in blue below.
composite
Is 1376 prime or composite?
