HCF & LCM Level 1

This structured exam mimics the quantitative aptitude progression found in top-tier competitive assessments, scaling in difficulty to test both speed and analytical depth regarding the Highest Common Factor (HCF) and Lowest Common Multiple (LCM).

• Level 1: Foundation & Speed (50 Questions)

  • Target: Designed to test rapid calculation and basic conceptual applications. Candidates are expected to solve these within 40–50 minutes.

  • Core Calculations: Direct computation of HCF and LCM for large integers, decimals, and fractions using formulas such as: LCM of fractions = (LCM of numerators) / (HCF of denominators).

  • Fundamental Properties: Questions revolving around the golden rule: Product of two numbers = HCF * LCM.

  • Standard Word Problems: Classic scenarios including "traffic lights changing simultaneously," "bells tolling together," and finding the maximum length of a scale to measure exact dimensions of different rooms.
