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.
