To determine if 1359 is a prime number or a composite number, we simply look at the factors for 1359.
If the factors of 1359 are only 1359 and 1, then we know that 1359 is a prime number. Otherwise, 1359 is a composite number.
To explain better, if 1359 is only divisible by 1 and 1359, then it is a prime number, and if 1359 is divisible by more than 1359 and 1, then it is a composite number.
The factors of 1359 are as follows:
1, 3, 9, 151, 453, 1359
Therefore, since 1359 is divisible by more than one and itself, the answer to the
question "Is 1359 prime or composite?" is highlighted in blue below.
composite
Is 1360 prime or composite?
