HCF Master

HCF Master HCF Master is a clear and visual calculator for finding the Highest Common Factor (HCF / GCD) and Lowest Common Multiple (LCM) of two or three numbers. Instead of showing only the final answer, HCF Master presents the calculation graphically so you can clearly follow how the result is obtained. The app includes two independent calculation methods. Common-Division Ladder See the numbers divided progressively using a clear ladder-style presentation. The app visually distinguishes: • Factors used for both HCF and LCM • Factors used for LCM only • Each intermediate calculation • Final HCF and LCM values Factor-Listing Method Use the traditional approach by viewing: • All factors of each number • Common factors • Highest common factor • Multiples of each number • First common multiple Three Ways to View the Solution Step Move through the calculation one stage at a time. Auto Watch the solution progress automatically. Full Display the complete calculation immediately. Key Features • Calculate HCF and LCM together • Supports two or three numbers • Common-division ladder method • Traditional factor-listing method • Step-by-step solution • Automatic presentation • Full solution view • Graphical calculation presentation • Clear distinction between HCF and LCM factors • Simple number input • Fast local calculations • Works without an internet connection • No account required HCF Master is designed to make HCF and LCM calculations faster, clearer and easier to understand.
