To determine if 1356 is a prime number or a composite number, we simply look at the factors for 1356.
If the factors of 1356 are only 1356 and 1, then we know that 1356 is a prime number. Otherwise, 1356 is a composite number.
To explain better, if 1356 is only divisible by 1 and 1356, then it is a prime number, and if 1356 is divisible by more than 1356 and 1, then it is a composite number.
The factors of 1356 are as follows:
1, 2, 3, 4, 6, 12, 113, 226, 339, 452, 678, 1356
Therefore, since 1356 is divisible by more than one and itself, the answer to the
question "Is 1356 prime or composite?" is highlighted in blue below.
composite
Is 1357 prime or composite?
