## A science educator wants to demonstrate common factors using real-world data. What is the greatest common factor of 72 and 90? Curious minds often ask: How can a number like 72 and another like 90 reveal shared patterns in the world around us? In classrooms, data-driven learning turns everyday numbers into fascinating insights—like discovering the greatest common factor, or GCF, a key tool in understanding shared multiples and relationships between numbers. For science educators using real-world data, this concept opens powerful pathways to teach logic, patterns, and problem-solving. The question—*What is the greatest common factor of 72 and 90?*—might seem simple, but it’s a gateway to deeper thinking about how numbers interact. The GCF is defined as the largest integer that divides both
