The lcm is the “lowest common denominator” (lcd) that can be used before fractions can be added, subtracted or compared. The lcm of more than two integers is also well-defined: it is the smallest positive integer that is divisible by each of them.

How is LCM used in our daily life?
To split things into smaller sections. To equally distribute any number of sets of items into their largest grouping. To figure out how many people we can invite. To arrange something into rows or groups.
What is LCM and HCF used for?
defines the greatest factor present in between given two or more numbers, whereas L.C.M. defines the least number which is exactly divisible by two or more numbers. H.C.F. is also called the greatest common factor (GCF) and LCM is also called the Least Common Divisor.
Where is GCD and LCM used in practical life?
We find their use in measurements and construction fields. If we have LCM and GCD, we can find the product of numbers.
Who invented LCM?
mathematician Euclid
… algorithm, procedure for finding the greatest common divisor (GCD) of two numbers, described by the Greek mathematician Euclid in his Elements (c. 300 bc). The method is computationally efficient and, with minor modifications, is still used by computers.
What is the purpose of HCF?
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.
Who invented HCF?
Euclid discovered the method for finding the HCF.
What problems can be solved using LCM?
LCM Problems may be asking you:
- about an event that is or will be repeating over and over.
- to purchase or get multiple items in order to have enough.
- to figure out when something will happen again at the same time.
Is LCM and GCD same?
The least common multiple (LCM) of two integers is the smallest positive integer that is a multiple of both. The greatest common divisor (GCD) of two integers is the largest positive integer dividing both. The product of the two numbers is the product of the LCM and the GCD.
Who created algebra?
Muhammad ibn Musa al-Khwarizmi
Muhammad ibn Musa al-Khwarizmi was a 9th-century Muslim mathematician and astronomer. He is known as the “father of algebra”, a word derived from the title of his book, Kitab al-Jabr.
Is GCD same as HCF?
The greatest common divisor (GCD) of two or more numbers is the greatest common factor number that divides them, exactly. It is also called the highest common factor (HCF). For example, the greatest common factor of 15 and 10 is 5, since both the numbers can be divided by 5.
What is HCM math?
A common factor is a factor that is shared by two or more numbers. For example, a common factor of 8 and 10 is 2, as 2 is a factor of 8, and 2 is also a factor of 10.
What is the smallest multiple of 10?
The smallest multiple of 10 is 1 multiplied by 10, i.e., 10. The other consecutive multiples of 10 can be found by multiplying 10 by 2, 3, 4, and 5, respectively. So, the first five multiples of 10 are: {10,20,30,40,50}. Now we will find the factors of multiples of 20.
How do you solve HCM?
How to find HCF by Prime Factorization?
- Step 1: Find the prime factors of the given numbers. In this case, the prime factors of 24 = 2 × 2 × 2 × 3, the prime factors of 36 = 2 × 2 × 3 × 3.
- Step 2: Multiply the prime factors that are common to both the numbers.
- Step 3: Therefore, the HCF of 24 and 36 is 12.
What is an example of a LCM word problem?
Find the lowest number which is more by 6 to be divided by 25, 40 and 60 exactly. We find the L.C.M. of 25, 40 and 60. Therefore, the required number is 600 + 6 = 606.
What is LCM in algorithm?
The least common multiple (lcm) of a and b is their product divided by their greatest common divisor (gcd) ( i.e. lcm(a, b) = ab/gcd(a,b) ).The Euclidean algorithm is generally how the gcd is computed.
How do you write an LCM for an algorithm?
Algorithm of LCM
Step 1: Initialize the positive integer variables A and B. Step 2: Store the common multiple of A & B into the max variable. Step 3: Validate whether the max is divisible by both variables A and B. Step 4: If max is divisible, display max as the LCM of two numbers.
Can we find LCM using Euclidean algorithm?
The Euclidean Algorithm is an efficient way of computing the GCD of two integers. It was discovered by the Greek mathematician Euclid, who determined that if n goes into x and y, it must go into x-y.The least common multiple , also known as the LCM, is the smallest number that is divisible by both integer a and b.
Who invented 0?
mathematician Brahmagupta
The first modern equivalent of numeral zero comes from a Hindu astronomer and mathematician Brahmagupta in 628. His symbol to depict the numeral was a dot underneath a number.
Who is the king of math?
