Step 1:
I'll solve this step-by-step using the specified LaTeX formatting guidelines:

Step 2:
: Find the factors of the numerator 51

51 = 3 \times 17

Step 3:
: Find the factors of the denominator 60

60 = 2^{2} \times 3 \times 5

Step 4:
: Identify the common factors

The common factor between 51 and 60 is 3.

Step 5:
: Divide both numerator and denominator by the greatest common factor (3)

\frac{51}{60} = \frac{51 \div 3}{60 \div 3} = \frac{17}{20}

Step 6:
: Verify the reduction

- Original fraction: $$\frac{51}{60}
- Reduced fraction: \frac{17}{20} - Common factor used: 3

Final Answer

The greatest common factor is 3, which reduces 51 / 60 to 17 / 20 in its lowest terms.
