## FAQs on Examples: Applications of HCF and LCM - 2 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) have various applications in real life. They are commonly used in fields such as mathematics, computer science, and engineering. In mathematics, HCF and LCM are used to solve problems related to fractions, ratios, and proportions. In computer science, they are used in algorithms and data structures. In engineering, they are used to find the least common multiple of different components' frequencies or to simplify complex electrical circuits.
 2. How can HCF and LCM be used in scheduling tasks?
Ans. HCF and LCM can be used in scheduling tasks to find the least common multiple of the task durations. By finding the LCM, we can determine the minimum time required to complete all the tasks simultaneously. This helps in optimizing the scheduling of tasks and avoiding conflicts or delays.
 3. How are HCF and LCM used in solving problems related to ratios and proportions?
Ans. HCF and LCM are used in solving problems related to ratios and proportions by finding the common factors or multiples of the given numbers. HCF is used to simplify ratios by dividing both the numerator and denominator by the highest common factor. LCM is used to find the least common multiple of the denominators in order to add or subtract fractions with different denominators.
 4. Can HCF and LCM be used in simplifying complex electrical circuits?
Ans. Yes, HCF and LCM can be used in simplifying complex electrical circuits. In circuit analysis, HCF is used to find the highest common factor of the frequencies of different components. This helps in determining the fundamental frequency of the circuit. LCM is used to find the least common multiple of the frequencies, which is important in synchronizing the operation of various components.
 5. How are HCF and LCM used in finding the optimal packaging for products?
Ans. HCF and LCM are used in finding the optimal packaging for products by considering the dimensions of the products and the available packaging options. HCF is used to find the common factor of the dimensions, which helps in determining the common unit of measurement for packaging. LCM is used to find the least common multiple of the dimensions, which helps in determining the optimal size of the packaging to minimize wastage and maximize efficiency.
