What is LCM of 43 and 50
Given Numbers are 43, 50
We can find the LCM of 43, 50 using the brute force method, prime factorization method, or GCD method.
To use brute force method, list the multiples of 43 and 50
Multiples of 43 =43,86,129,172,215,258,301,344,387,430,473,516,559,602,645,688,731,
Multiples of 50 =50,100,150,200,250,300,350,400,450,500,550,600,650,700,750,800,850,
Now, get the least common multiple of 43, 50 which is 2150
So, the LCM of 43, 50 is 2150.
Least Common Multiple (LCM) of 43 and 50 with the help of Prime Factorisation
One method for determining the LCM of 43 and 50 is to compare the prime factorization of each number. You can find the prime factorization for each number by following the instructions below:
Here is 43's prime factorization:
| 43 | 43 |
| 1 |
Prime factors of 43 are 43.
43 = 431
And this is 50's prime factorization:
| 2 | 50 |
| 5 | 25 |
| 5 | 5 |
| 1 |
Prime factors of 50 are 2,5.
50 = 21×52
When comparing the prime factorization of these two numbers, look for the highest power to which each prime factor is raised. In this case, the following primary factors must be considered:43, 2,5
.21×52×431 = 2150
This shows that the LCM of 43 and 50 is 2150.
How to Calculate the LCM of 43 and 50 Using Common Multiples
The first step in determining the Least Common Multiple of 43 and 50 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 43 and 50:
Lets look at the first ten multiples of these numbers, 43 and 50:
43,86,129,172,215,258,301,344,387,731 are the first ten multiples of 43.
50,100,150,200,250,300,350,400,450,850 are the first ten multiples of 50.
You can continue to list the multiples of these numbers until you find a match. Once you have found a match, or several matches, the Least Common Multiple is the smallest of these matches. The first matching multiple(s) of 43 and 50, for example, are 516, 731, and 800. 2150 is the least common multiple since it is the smallest.
43 and 50 have an LCM of 2150.
Least Common Multiple of 43 and 50 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 43 and 50, than apply into the LCM equation.
GCF(43,50) = 1
LCM(43,50) = ( 43 × 50) / 1
LCM(43,50) = 2150 / 1
LCM(43,50) = 2150
