Answer
$2^{3}\times13$
Work Step by Step
In order to find the prime factorization of 104, we can try to divide 104 by the first prime, 2.
$104\div2=52$
Try to divide 52 by 2.
$52\div2=26$
Try to divide 26 by 2.
$26\div2=13$
13 itself is a prime number, so we cannot simplify any more. The prime factorization of 104 is $2\times2\times2\times13=2^{3}\times13$.
