## FAQs on Examples: Applications of HCF and LCM - 1 Video Lecture - Mathematics & Pedagogy - CTET & State TET

 1. What is the application of HCF and LCM in real life?
Ans. HCF (Highest Common Factor) and LCM (Least Common Multiple) are mathematical concepts that have several practical applications in real life. They are commonly used in fields such as engineering, computer science, and finance. HCF is used in simplifying fractions, finding the greatest common divisor of numbers, and in cryptography. LCM is used in finding the least common multiple of numbers, scheduling tasks, and in solving problems related to periodicity.
 2. How can HCF and LCM be used in engineering?
Ans. In engineering, HCF and LCM are used in various applications. For example, in electrical engineering, HCF is used in simplifying complex circuits and finding the common factors between different components. LCM is used in synchronization of signals and determining the time interval for periodic events. These concepts are also used in civil engineering for calculating the materials required for construction based on common factors and multiples.
 3. Can HCF and LCM be used in finance?
Ans. Yes, HCF and LCM have applications in finance as well. For instance, in investment planning, LCM is used to calculate the time it takes for multiple investments to align and yield returns simultaneously. It helps in determining the common multiples of different investment periods. HCF is used in financial calculations when finding the common factors in interest rates, loan terms, or investment returns.
 4. How are HCF and LCM relevant in computer science?
Ans. In computer science, HCF and LCM are commonly used in algorithm design and optimization. They are used in solving problems related to scheduling tasks, resource allocation, and finding the optimal solution. HCF is used to find the common factors in memory allocation and disk space management. LCM is used in determining the duration of periodic events and in designing efficient algorithms.
 5. Are there any practical applications of HCF and LCM in everyday life?
Ans. Yes, HCF and LCM have practical applications in our everyday life as well. For instance, when planning an event or gathering, LCM can be used to determine the least common multiple of different durations, such as the time it takes for different guests to arrive or the intervals between activities. HCF can be used to simplify recipes, calculate the common factors in ingredient quantities, or determine the least wasteful way of dividing resources among people.
