**Why Understanding the Greatest Common Factor Matters in Soil Stability Analysis** Beneath the surface of everyday construction lies a hidden detail that shapes long-term foundation integrity: the greatest common factor (GCF) of soil cohesion values. For geotechnical engineers, identifying the GCF of measured soil parameters—like 84 kPa and 108 kPa cohesion—helps assess uniform stability across layers. As trends in infrastructure quality demand greater precision, understanding these fundamental calculations supports smarter design and risk mitigation. This article explores why this mathematical insight remains relevant, how engineers apply it, and what it means for building resilient structures across the United States. --- **Why A Geotechnical Engineer Must Assess the Greatest Common Factor of Soil Cohesion Values**
