Least Common Multiple

The content provides an in-depth exploration of the Least Common Multiple (LCM), its calculation methods, significance in various mathematical contexts, and strategies for enhancing number sense and intuition.
  • LCM is crucial for solving problems involving fractions, sets of different sizes, and is identical to the Least Common Denominator (LCD).
  • The process of finding the LCM can be simplified by using the prime factorization of numbers and identifying their Greatest Common Factor (GCF).
  • Understanding and applying the concept of LCM is essential for GRE test-takers, especially in problems disguised in word problems or fraction operations.
  • Developing number sense and intuition beyond memorized procedures is emphasized for superior performance in math sections of tests.
  • An exercise for building number sense involves daily practice with randomly chosen pairs of two-digit numbers to estimate their GCF and LCM before verifying with the outlined procedure.
