Answer

$11\times13$

Work Step by Step

A number is prime if it has only two factors: 1 and itself. We know that the factors of 143 are 1, 11, 13, and 143. 11 is a prime number, so we can divide 143 by 11. $143\div11=13$ 13 is also a prime number. Therefore, the prime factorization of 143 is $11\times13$.
