To determine if 1353 is a prime number or a composite number, we simply look at the factors for 1353.
If the factors of 1353 are only 1353 and 1, then we know that 1353 is a prime number. Otherwise, 1353 is a composite number.
To explain better, if 1353 is only divisible by 1 and 1353, then it is a prime number, and if 1353 is divisible by more than 1353 and 1, then it is a composite number.
The factors of 1353 are as follows:
1, 3, 11, 33, 41, 123, 451, 1353
Therefore, since 1353 is divisible by more than one and itself, the answer to the
question "Is 1353 prime or composite?" is highlighted in blue below.
composite
Is 1354 prime or composite?
