What is the physical meaning of LCM?
Lowest Common Multiple (LCM): The smallest number (other than zero) that is the common multiple of any two or more given natural numbers are termed as LCM. For example, LCM of 6, 8, and 12 is 24.
How do you use HCF and LCM in real life?
This problem can be solved using H.C.F. because we are cutting or “dividing” the strips of cloth into smaller pieces (Factor) of 72 and 90 (Common) and we are looking for the widest possible strips (Highest). Priyanka should cut each piece to be 18 inches wide . L.C.M. : we use find L.C.M.
How do we use HCF in real life?
Applications of HCF It is used to split things into smaller sections, to arrange something into rows or groups, to distribute more numbers of items to large groups, and to figure out how many people we have to invite and so on when we want to split things into smaller sections.
Why is LCM and HCF important?
L.C.M and H.C.F of two or more numbers help in finding out quick solutions and thus reduce time during examinations. The concept of L.C.M. is important to solve problems related to racetracks, traffic lights, etc.
What is LCM and HCF Quora?
HCF= highest common factor. The HCF of two or more numbers is the largest common factor of the given numbers. It is the greatest number which divides the two or more given numbers. LCM = least common multiple. The LCM of two or more numbers is the smallest number that is a common multiple of two or more numbers.
How do you find the HCF and LCM in statement sums?
When we have to find a number larger than given numbers, then we find LCM. If we have to find smaller number, then we find HCF .
Where do we use LCM?
In math problems where we pair two objects against each other, the LCM value is useful in optimizing the quantities of the given objects. Also, in computer science, the LCM of numbers helps design encoded messages using cryptography.
What is the difference between HCF and LCM with examples?
LCM : The least number which is exactly divisible by each of the given numbers is called the least common multiple of those numbers. For example, consider the numbers 3, 31 and 62 (2 x 31). HCF : The largest number that divides two or more numbers is the highest common factor (HCF) for those numbers.
What is the difference between LCM and HCF?
If one of the numbers is a factor of the other number and vice versa if the greater number is a multiple of the smaller number,then the smaller number is the hcf and the larger number is the lcm. For example,consider 12 and 36.
How do you calculate LCM?
Let’s find the LCM of 30 and 45. One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.
What does LCM mean in math?
Least Common Multiple (LCM) In Mathematics, LCM of any two is the value which is evenly divisible by the two given numbers. The full form of LCM is Least Common Multiple. It is also called the Least Common Divisor (LCD).
How to calculate HCF?
Write down each number as the product of its prime factors.
