How is lcm used in our daily life

How wide should she cut the strips? This problem can be solved using H. So we can say that. Priyanka should cut each piece to be 45 inches wide. We Use L. Method in Following Fields :. About an event that is or will be repeating over and over. To purchase or get multiple items in order to have enough. To analyse when something will happen again at the same time. Real Life Example: Ram exercises every 8 days and Deepika every 4 days.

LCM Least common multiple is the least number which is exactly divisible by each one of the given numbers. It is used to solve problems related to racetracks, traffic lights, predict when an event occurs again over the same period, etc.

Here are some ways the concept of LCM is applied in our everyday life:. Repetitive tasks and events: The traffic controllers have to set the timings of traffic lights so that all lights are not green simultaneously, especially in busy day timings. As this may create problems and they have to be set for a few minutes only.

A traffic controller takes the timings of nearby places in the same area and calculates the LCM of all traffic stops to set the timing for each signal. We have to bring both of them to the same denominator to solve infractions with different denominators.

This requires first bringing them to have a common denominator by using LCM. Think out when something will happen again at the same time. In those values,least value is This is what we are finding by taking L.

M of two numbers without writing tables of those numbers. To understand this topic much better let us consider the following example. Two boys run on a circular track.

They start at the same time. They take 12 minutes and 10 minutes respectively to go round once. Find at what time they will run together?

Here two persons A and B are running in a circular track. They start at the same time and they are taking 12 minutes and 10 minutes respectively to go round once. So I did a research […]. I have spent 13 yrs in South India. Bengaluru, Secundrabad and Hyderabad to be precise. Each morning we would wake up with the very pleasant sound of mantras.

Initially it was irritation that slowly transformed to tuning my morning chores. When I […]. Most members are working from home and earning handsome Rs 50 thousand to 10 Lakh Per month! They sell genuine products directly sourced from the manufacturers or from the wholesalers. If you wish to become an entrepreneur, you too […]. I am very sure we must have learnt the real reason of where LCM should be used in the school days but I guess either I never paid attention or was never explained the real life usage.

So thank fully my son asked me this question, "Why should we learn LCM mom? Have you ever watched how beautifully the Diwali lighting glow one after another, few very fast and others slower.

So what time will it be when all the lights glow at one time!
