To determine if 3159 is a prime number or a composite number, we simply look at the factors for 3159.
If the factors of 3159 are only 3159 and 1, then we know that 3159 is a prime number. Otherwise, 3159 is a composite number.
To explain better, if 3159 is only divisible by 1 and 3159, then it is a prime number, and if 3159 is divisible by more than 3159 and 1, then it is a composite number.
The factors of 3159 are as follows:
1, 3, 9, 13, 27, 39, 81, 117, 243, 351, 1053, 3159
Therefore, since 3159 is divisible by more than one and itself, the answer to the
question "Is 3159 prime or composite?" is highlighted in blue below.
