The prime factorization of 125 is 5^3.

Explanation:

To find the prime factorization, divide 125 by only prime numbers. Remember that prime numbers are whole numbers greater than 1 that are only evenly divisible by themselves and 1.
{2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, etc.}

Since 125 ends in 5, it is evenly divisible by 5, which is a prime number. (How convenient!)

125 -: 5 = 25

25 now has to be factored into its prime factors.

25 = 5 * 5

So, the prime factorization of 125 is

125 = 5*5*5 = 5 ^3
