CorrectA soil scientist is analyzing soil samples from three farms to compare nutrient levels. She collects 24 samples from Farm A, 36 from Farm B, and 40 from Farm C. She wants to divide all samples into equal-sized groups for testing, with each group containing only samples from the same farm and all groups being as large as possible. What is the maximum number of samples that can be in each group? - Deep Underground Poetry
Unlocking Farm Efficiency: How a Soil Scientist Organizes Samples for Precision Research
In an era where data-driven farming is reshaping U.S. agriculture, careful sample management is critical. A soil scientist recently faced a common yet crucial challenge: analyzing nutrient levels across multiple farms while ensuring consistent testing conditions. With 24 samples from Farm A, 36 from Farm B, and 40 from Farm C, her goal was to divide the total into equal, farm-specific groups—each solely containing samples from one farm. This process mirrors how modern farming operations scale accuracy and efficiency, optimizing inputs like fertilizers and irrigation. With mobile-first research workflows gaining traction, such structured sampling enables faster, reliable insights.

Why Soil Sampling Consistency Matters in Performance Research
Organizing soil samples by farm first allows precise nutrient comparison, revealing subtle differences in soil health across locations. In the U.S., where regional agricultural practices vary widely, standardized sampling supports better decision-making for crop yields and sustainability. Recent agricultural trends highlight the growing need for data transparency and system optimization, making consistent sample grouping both a scientific and operational priority. With increasing adoption of smart farming tools, methodical sample division enables farmers and researchers to act on real-time data with confidence.
Finding the Perfect Group Size: The Math Behind Equal Farm Testing
To determine the largest possible equal-sized groups, the scientist must identify the greatest common divisor (GCD) of 24, 36, and 40. This number represents the maximum sample count per group—ensuring each farm’s samples are evenly distributed without leftover. The GCD calculation reveals shared factors: 24 factors into 2³×3, 36 into 2²×3², and 40 into 2³×5. The only prime factor common to all is 2, raised to the lowest power—2¹. Thus, the highest possible sample size per group is 2.
