Greatest Common Factor and Least Common Multiple: Sample FAST Questions

Students find the greatest common factor (GCF) and least common multiple (LCM) of two whole numbers, both as straight computation and within real-world contexts. Typical applications include splitting items into equal groups (GCF) or figuring out when two repeating events line up again (LCM).

How the FAST tests this benchmark

FAST items include equation editor questions asking for the GCF or LCM of two numbers and multiple choice word problems where students must recognize whether a situation calls for GCF or LCM.

Skills students need

  • Find the greatest common factor of two whole numbers
  • Find the least common multiple of two whole numbers
  • Solve real-world problems using GCF and LCM
