Math Problem Statement

solve by prime factorizing

Solution

To solve by prime factorization, you can follow these steps for various types of problems:

Example Problem:

Let's say we want to find the prime factorization of 180.

Steps to solve by prime factorizing:

  1. Divide by smallest prime: Start with the smallest prime number, 2, and divide 180 by 2. 180÷2=90180 ÷ 2 = 90
  2. Continue dividing by 2: Divide 90 by 2 again. 90÷2=4590 ÷ 2 = 45
  3. Next smallest prime (3): 45 is not divisible by 2 anymore, so we move to the next smallest prime, 3. 45÷3=1545 ÷ 3 = 15
  4. Continue dividing by 3: Divide 15 by 3 again. 15÷3=515 ÷ 3 = 5
  5. Final division (5): 5 is a prime number, so we stop here.

Thus, the prime factorization of 180 is: 180=22×32×5180 = 2^2 × 3^2 × 5
