What is LCM of 54 and 61

Given Numbers are 54, 61

We can find the LCM of 54, 61 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 54 and 61

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

Multiples of 61 =61,122,183,244,305,366,427,488,549,610,671,732,793,854,915,976,1037,

Now, get the least common multiple of 54, 61 which is 3294

So, the LCM of 54, 61 is 3294.

Least Common Multiple (LCM) of 54 and 61 with the help of Prime Factorisation

One method for determining the LCM of 54 and 61 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 54's prime factorization:


2 54
3 27
3 9
3 3
1

Prime factors of 54 are 2,3.

54 = 21×33

And this is 61's prime factorization:


61 61
1

Prime factors of 61 are 61.

61 = 611

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: 2,3,61

.

21×33×611 = 3294

This shows that the LCM of 54 and 61 is 3294.

How to Calculate the LCM of 54 and 61 Using Common Multiples

The first step in determining the Least Common Multiple of 54 and 61 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 54 and 61:

Lets look at the first ten multiples of these numbers, 54 and 61:

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

61,122,183,244,305,366,427,488,549,1037 are the first ten multiples of 61.

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 54 and 61, for example, are 648, 918, and 976. 3294 is the least common multiple since it is the smallest.

54 and 61 have an LCM of 3294.

Least Common Multiple of 54 and 61 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 54 and 61, than apply into the LCM equation.

GCF(54,61) = 1
LCM(54,61) = ( 54 × 61) / 1
LCM(54,61) = 3294 / 1
LCM(54,61) = 3294
