To determine if 1395 is a prime number or a composite number, we simply look at the factors for 1395.
If the factors of 1395 are only 1395 and 1, then we know that 1395 is a prime number. Otherwise, 1395 is a composite number.
To explain better, if 1395 is only divisible by 1 and 1395, then it is a prime number, and if 1395 is divisible by more than 1395 and 1, then it is a composite number.
The factors of 1395 are as follows:
1, 3, 5, 9, 15, 31, 45, 93, 155, 279, 465, 1395
Therefore, since 1395 is divisible by more than one and itself, the answer to the
question "Is 1395 prime or composite?" is highlighted in blue below.
