Composite.
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.
143 is composite.
The number 143 is a composite number, which means it has more than two factors. The factors of 143 are 1, 11, 13, and 143. These numbers can be multiplied together to give the original number, 143.
