An online lcm calculator helps to find the least common multiple (lcm) of the two to ten or more numbers step-by-step by using different LCM calculation methods. This online least common factor calculator allows you to estimate the lowest quantity that is the multiple of two or more numbers.
Keep reading to know about how to find the least common multiple with different methods step-by-step, formulas for every method, and many other lcm related terms.
Now, let’s start with the basic definition.
It is also known as Lowest Common Multiple is a basic mathematical function that determines the smallest integer that is divisible by each one of the integers. It is helpful before performing addition and subtraction of fractions with different denominators, to convert all fractions so that denominator is the least common factor. In this case, lcm is also referred to as the Least Common Denominator (LCD).
So, simply consider our least common multiple calculator that helps you to find the LCM step-by-step for your mathematical problem.
Also, calculator-online provided the best fraction calculator that helps in adding, subtracting, multiplying, and dividing 2 or 3 fractions.
Here are the five different LCM calculation methods discussed and manual calculation for each method. This lcm finder uses the following formulas for each method to find lcm of the given data set.
The LCM can be calculated by listing all the multiples of the given integers until the matched integer is reached. This method is also known as the Brute-Force method.
Here we have an example to clear the concept of calculation by listing the multiples.
What is the least common factor of 8,12 and 16?
Multiples of 8 = 8,16,24,32,40,48,56,64
Multiples of 12 = 12,24,36,48,60,72
Multiples of 16 = 16,32,48,64,80
Here, the smallest number which is on all the lists is 48.
So, the LCM of 8,12,16 is 48.
Another method to find the lcm of the given data set is the prime factorization method. Prime factorization includes the splitting of each number which is compared to the product of prime numbers. Then the LCM calculate by multiplying the highest power of every prime with one another. This method is more efficient than the Brute-Force method. You can also use this free prime factorization calculator to make the prime factors of any number. Let’s try an example of this method:
Find out the lcm of 10,15 and 20?
Prime factors of 10: 2 × 5
Prime factors of 15: 3 × 5
Prime factors of 20: 2 × 2 × 5
Then,LCM is = 5 × 2 × 2 × 3
The third feasible method to calculate the lcm of the integers is by greatest common factor method.It is also known as the greatest common divisor method. In GCF method, all you need to divide the product of numbers by their greatest common factor. The formula to find lcm with this method is as follow:
LCM (a,b) = a * b / GCF
Find the LCM of 4 and 10?
The GCF of 4 and 10 = 2
LCM (4 ,10) = 4 * 10 / 2
LCM (4 ,10) = 20
The cake method finds the lcm of the given numbers with help of simple division. People use the cake/ladder method to find the least common multiple because it is the easiest way to determine lcm. Let’s try an example for this method.
Find the lcm of 8,12,14,20?
Write the numbers in a row.
Divide the numbers by a prime number which is divisible by two or more numbers.
The lcm of 8,12,14,20 = 2 × 2 × 2 × 3 × 7 × 5
The division method is the last method that is used by our lcm calculator to find the lowest common multiple. This lowest common multiple calculator allows you to find the lcm of any set of numbers by the long division of numbers with its prime factors. We have an example to clear the concept.
Find out the lcm of 6,12,15?
Write the numbers in a row.
Divide the numbers by a prime number which is divisible by two or more numbers. Divide until the last term will be all one’s.
The LCM of 8,12,14,20 = 2 × 2 × 2 × 3 × 5 × 7
Let’s take a look at the given properties:
The lcm of the two numbers is commutative,i;e
LCM (a,b) = LCM (b,a)
The lowest common multiple of three numbers is associative,
LCM (a,b,c) = LCM (LCM (a,b),c) = LCM(a,LCM(b,c))
The lowest common multiple of numbers is distributive,
LCM (da,db,dc) = dLCM (a,b,c)
Where d is any constant.
A simple lcm calculator will enable you to find the lowest common factor (lcm) or least common denominator (lcd) of two or n numbers. This lcm finder helps to calculate lcm step-by-step corresponding to the following methods:
Finding the least common denominator of numbers becomes easy with this least common factor calculator. All you need to follow the given steps for finding lcm.
Once you fill up all the field of this least common finder calculator, this will show you,
In a stationary, blue pencils come in a package of 16 while red pencils come in the package of 19. If we want to purchase equal numbers of both pencils, then find the smallest number of blue pencils that we must buy.
In this real-world problem, it is challenging to know the answer, so finding the least common denominator is an effective measure to determine the answer.
So, this lcm calculator shows the step-by-step calculation of your real life problems.
The least common multiple of 12,15 and 21 is 420.
8 is the least common multiple of 4 and 8. This lcm calculator helps you to calculate the lcm of numbers according to different methods.
The least common multiple (LCM) of 24 and 36 is the smallest number which is exactly divisible by 24 and 36.72 is the smallest number which divides the 24 and 36 and gives zero remainders.
For finding the least common multiple by prime factorization method, we have to write the factors of both numbers,
Prime factors of 24 = 2 × 2 × 2 × 3
Prime factors of 300 = 2 × 2 × 3 × 5 × 5
LCM = 2 × 2 × 3 × 2 × 5 × 5
LCM = 600
This least common multiple calculator determines the lcm of 15 and 24 the smallest number is 60 which exactly divides the 15 and 24. So, the LCM of 14 and 24 is 60.
The multiple is a number that you get when multiplying a number with the whole number. Example: the multiples of 9 are 9,18,27,36,45,54,63,72,81,…
The least common multiple (LCM) of 10,15 and 20 is 60 which is determined by multiplying the common & uncommon prime factors.
The least common factor is very helpful in the real world problems as well as in mathematics, especially for adding, subtracting, and comparing fractions. The LCM of the numbers helps in finding a quick solution and saves the time of students during the examination. Also, an online lcm calculator will perform lcm calculations for larger or larger sets of numbers accurately.
