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.

No 429 is not prime. A prime number is a number where the only multiples of it are "1" and the number itself. 429 / 3 = 143. So 3 x 143 are also factors.Prime numbers do not end in 0,2,4,5,6,8; excluding 2 (Two), 22 is not prime but 2 is because 1 x 2 = 2. And remember the definition says a prime number is a number that can only be multiplied by 1 and itself.
