91125 ÷ 3 = 30375

30375 ÷ 3 = 10125

10125 ÷ 3 = 3375

3375 ÷ 3 = 1125

1125 ÷ 3 = 375

375 ÷ 3 = 125

125 ÷ 5 = 25

25 ÷ 5 = 5

5 ÷ 5 = 1

The prime factors of 91125 are 3 and 5. The prime factorization of 91125 is: 3⁶ × 5².

The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -

Step 1: Firstly, 91125 is divided by 3 to get 30375.

Step 2: Now divide 30375 by 3 to get 10125.

Step 3: Then divide 10125 by 3 to get 3375.

Step 4: Divide 3375 by 3 to get 1125.

Step 5: Divide 1125 by 3 to get 375.

Step 6: Divide 375 by 3 to get 125.

Step 7: Divide 125 by 5 to get 25.

Step 8: Divide 25 by 5 to get 5. Here, 5 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 91125 is: 3⁶ × 5².
