To determine if 354 is a prime number or a composite number, we simply look at the factors for 354.
If the factors of 354 are only 354 and 1, then we know that 354 is a prime number. Otherwise, 354 is a composite number.
To explain better, if 354 is only divisible by 1 and 354, then it is a prime number, and if 354 is divisible by more than 354 and 1, then it is a composite number.
The factors of 354 are as follows:
1, 2, 3, 6, 59, 118, 177, 354
Therefore, since 354 is divisible by more than one and itself, the answer to the
question "Is 354 prime or composite?" is highlighted in blue below.
composite
Is 355 prime or composite?
