To factor 80 using the factor tree method, follow these steps:

1. **Start with the number 80** and find two numbers that multiply to give 80. For example:
   \[
   80 = 8 \times 10
   \]

2. **Factor 8** into two numbers:
   \[
   8 = 4 \times 2
   \]

3. **Factor 4** into two numbers:
   \[
   4 = 2 \times 2
   \]
   So, 8 can be factored as \(2 \times 2 \times 2\).

4. **Factor 10** into two numbers:
   \[
   10 = 5 \times 2
   \]

5. **Combine all the factors**: 
   \[
   80 = 2 \times 2 \times 2 \times 2 \times 5
   \]

Therefore, the prime factorization of 80 is:
\[
80 = 2^4 \times 5
\]
