To determine if 250 is a prime number or a composite number, we simply look at the factors for 250.
If the factors of 250 are only 250 and 1, then we know that 250 is a prime number. Otherwise, 250 is a composite number.
To explain better, if 250 is only divisible by 1 and 250, then it is a prime number, and if 250 is divisible by more than 250 and 1, then it is a composite number.
The factors of 250 are as follows:
1, 2, 5, 10, 25, 50, 125, 250
Therefore, since 250 is divisible by more than one and itself, the answer to the
question "Is 250 prime or composite?" is highlighted in blue below.
composite
Is 251 prime or composite?
OK. Now you know that 250 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
