In this chapter we will try to understand basics and advanced concept of GCF (or HCF) and LCM. After that we will solve questions for our exam practice.
In short we will cover following topics
1. What is the Greatest Common Factor (GCF) or Highest Common Factor (HCF)
2. What is the Lowest Common Multiple (LCM)
3. How to find GCF or HCF of numbers
4. How to find LCM of different numbers
5. Tricks and shortcuts to solve HCF and LCM questions
6. Questions with step by step answers for your practice. The questions are designed keeping in mind the requirement of entrance exams like GMAT, CAT, NMAT, SNAP, CMAT, MAT, SSC, SSC-CGL, SSC-CHSL, NDA, AFCAT, SBI PO, SBI Clerk, IBPS PO, IBPS Clerk
