To determine if 353 is a prime number or a composite number, we simply look at the factors for 353.
If the factors of 353 are only 353 and 1, then we know that 353 is a prime number. Otherwise, 353 is a composite number.
To explain better, if 353 is only divisible by 1 and 353, then it is a prime number, and if 353 is divisible by more than 353 and 1, then it is a composite number.
The factors of 353 are as follows:
1, 353
Therefore, since 353 is divisible by only one and itself, the answer to the
question "Is 353 prime or composite?" is highlighted in blue below.
prime
