What is LCM of 46 and 54

Given Numbers are 46, 54

We can find the LCM of 46, 54 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 46 and 54

Multiples of 46 =46,92,138,184,230,276,322,368,414,460,506,552,598,644,690,736,782,

Multiples of 54 =54,108,162,216,270,324,378,432,486,540,594,648,702,756,810,864,918,

Now, get the least common multiple of 46, 54 which is 1242

So, the LCM of 46, 54 is 1242.

Least Common Multiple (LCM) of 46 and 54 with the help of Prime Factorisation

One method for determining the LCM of 46 and 54 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 46's prime factorization:


2 46
23 23
1

Prime factors of 46 are 2,23.

46 = 21×231

And this is 54's prime factorization:


2 54
3 27
3 9
3 3
1

Prime factors of 54 are 2,3.

54 = 21×33

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: 2,23,3

.

21×33×231 = 1242

This shows that the LCM of 46 and 54 is 1242.

How to Calculate the LCM of 46 and 54 Using Common Multiples

The first step in determining the Least Common Multiple of 46 and 54 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 46 and 54:

Lets look at the first ten multiples of these numbers, 46 and 54:

46,92,138,184,230,276,322,368,414,782 are the first ten multiples of 46.

54,108,162,216,270,324,378,432,486,918 are the first ten multiples of 54.

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 46 and 54, for example, are 552, 782, and 864. 1242 is the least common multiple since it is the smallest.

46 and 54 have an LCM of 1242.

Least Common Multiple of 46 and 54 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 46 and 54, than apply into the LCM equation.

GCF(46,54) = 2
LCM(46,54) = ( 46 × 54) / 2
LCM(46,54) = 2484 / 2
LCM(46,54) = 1242
