To determine if 290 is a prime number or a composite number, we simply look at the factors for 290.
If the factors of 290 are only 290 and 1, then we know that 290 is a prime number. Otherwise, 290 is a composite number.
To explain better, if 290 is only divisible by 1 and 290, then it is a prime number, and if 290 is divisible by more than 290 and 1, then it is a composite number.
The factors of 290 are as follows:
1, 2, 5, 10, 29, 58, 145, 290
Therefore, since 290 is divisible by more than one and itself, the answer to the
question "Is 290 prime or composite?" is highlighted in blue below.
composite
Is 291 prime or composite?
