Least Common Multiple (LCM) of 43 and 48 with the help of Prime Factorisation
One method for determining the LCM of 43 and 48 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 48's prime factorization:
| 2 | 48 |
| 2 | 24 |
| 2 | 12 |
| 2 | 6 |
| 3 | 3 |
| 1 |
Prime factors of 48 are 2,3.
48 = 24×31
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, 2,3
.24×31×431 = 2064
This shows that the LCM of 43 and 48 is 2064.
How to Calculate the LCM of 43 and 48 Using Common Multiples
The first step in determining the Least Common Multiple of 43 and 48 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 43 and 48:
Lets look at the first ten multiples of these numbers, 43 and 48:
43,86,129,172,215,258,301,344,387,731 are the first ten multiples of 43.
48,96,144,192,240,288,336,384,432,816 are the first ten multiples of 48.
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 48, for example, are 516, 731, and 768. 2064 is the least common multiple since it is the smallest.
43 and 48 have an LCM of 2064.
Least Common Multiple of 43 and 48 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 48, than apply into the LCM equation.
GCF(43,48) = 1
LCM(43,48) = ( 43 × 48) / 1
LCM(43,48) = 2064 / 1
LCM(43,48) = 2064
