No. As long as there are more than two, the number's composite.

No. If it is divisible by any smaller integer, it is composite.

No because, all you have to know is your multiplication to help you.


Do you need to know all of the factors of a number in order to determine if it is a prime or composite?

Yes, you do. And know them well, or else you'll get it wrong! Well, not exactly. To determine that a number is prime you need to know that the number has exactly two factors, which means that there are no other factors. You know that a number is composite by finding just one factor that is neither one nor the number itself.


Do you need to know all of the factors of a number in order to determine if it prime or composite?

All natural numbers (counting numbers) greater than one are either prime or composite. If divisible by only one and the number itself, it is prime; if divisible by other natural numbers, then is composite. One is the only natural number that is neither prime nor composite.


Which is true about 143 It is a prime number It is a composite number It is a whole number that is neither prime nor composite or It is not a whole number?

We know that 143 is a whole number and that it has to be either prime or composite because all whole numbers other than 0 and 1 are one or the other. So, in order to determine if it is prime or composite, we need to know if any numbers besides 1 and 143 are factors. 1, 11, 13, and 143 are factors so 143 is a composite number.

Is 98 prime or composite and why?

A number which has more than two factors is called composite number. 98 is a composite number because it has more than two factors. Factors of 98: 1, 2, 7, 14, 49 and 98. In order to prove that a number is composite try to find a factor other than 1 and the number itself: Since 98 is an even number so it is divisible by 2, so 2 is one of the factors of 98. For now we know three factors of 98: 1, 2 and 98. So, 98 is a composite number since we have found more than two factors.


Is 328 composite or prime?

That '8' at the end reveals it to be an even number. Therefore, '2' is a factor, and the number is composite. There may be more factors, but all we need is one in order to say that it's not prime.


Is 1024 a prime number or a composite number?

1024 is a COMPOSITE NUMBER! this is because it is even.=============================================If it has any more factors in addition to '1' and itself, then it's composite.The factors of 1,024 are: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, and 1,024.As you can see, '1' and itself are not quite the only factors of 1,024 ... there are 9 more ...so it's a composite number.


Is five a composite number?

No, five is a prime number because there are only two whole numbers that when multiplied, equals five. (Those numbers are five and one.) In order for a number to be composite, it has to have factors other than itself and one.
