how to do factor tree method for 3 digit numbers ?

The factor tree method is a technique used to break down a number into its prime factors. Here's how you can use the factor tree method for a three-digit number:

### Steps to Perform the Factor Tree Method:

1. **Choose a Starting Factor**: 
   - Begin by selecting any two factors of the number (other than 1 and the number itself).
   - These factors should multiply to give the original number.

2. **Break Down the Factors**: 
   - If either of the factors is not a prime number, break it down further into its own factors.
   - Continue breaking down until all the factors are prime numbers.

3. **Prime Factorization**:
   - The prime factors are the "leaves" of your factor tree, i.e., the numbers at the ends of each branch.
   - Multiply all the prime factors together, and they should give you the original number.

### Example: Factor Tree of 180

1. **Start with the number 180**:
   - Choose two factors: \(180 = 2 \times 90\)

2. **Break Down 90**:
   - \(90 = 2 \times 45\)

3. **Break Down 45**:
   - \(45 = 3 \times 15\)

4. **Break Down 15**:
   - \(15 = 3 \times 5\)

5. **Complete Factor Tree**:
   - The factor tree for 180 is:
     ```
          180
         /   \
        2    90
            /  \
           2   45
              /  \
             3   15
                /  \
               3    5
     ```
   - Prime factors: \(2 \times 2 \times 3 \times 3 \times 5\)
   - Simplified as \(2^2 \times 3^2 \times 5\)

### Prime Factorization of 180:
\[
180 = 2^2 \times 3^2 \times 5
\]

### General Tips:
- Always start with the smallest prime number (2, 3, 5, etc.) if possible.
- A factor tree can be done in several ways, but the prime factors will always be the same.
