What is LCM of 122 and 126

Given Numbers are 122, 126

We can find the LCM of 122, 126 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 122 and 126

Multiples of 122 =122,244,366,488,610,732,854,976,1098,1220,1342,1464,1586,1708,1830,1952,2074,

Multiples of 126 =126,252,378,504,630,756,882,1008,1134,1260,1386,1512,1638,1764,1890,2016,2142,

Now, get the least common multiple of 122, 126 which is 7686

So, the LCM of 122, 126 is 7686.

Least Common Multiple (LCM) of 122 and 126 with the help of Prime Factorisation

One method for determining the LCM of 122 and 126 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 122's prime factorization:


2 122
61 61
1

Prime factors of 122 are 2,61.

122 = 21×611

And this is 126's prime factorization:


2 126
3 63
3 21
7 7
1

Prime factors of 126 are 2, 3,7.

126 = 21×32×71

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: 2,61, 3,7

.

21×32×71×611 = 7686

This shows that the LCM of 122 and 126 is 7686.

How to Calculate the LCM of 122 and 126 Using Common Multiples

The first step in determining the Least Common Multiple of 122 and 126 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 122 and 126:

Lets look at the first ten multiples of these numbers, 122 and 126:

122,244,366,488,610,732,854,976,1098,2074 are the first ten multiples of 122.

126,252,378,504,630,756,882,1008,1134,2142 are the first ten multiples of 126.

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 122 and 126, for example, are 1464, 2074, and 2016. 7686 is the least common multiple since it is the smallest.

122 and 126 have an LCM of 7686.

Least Common Multiple of 122 and 126 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 122 and 126, than apply into the LCM equation.

GCF(122,126) = 2
LCM(122,126) = ( 122 × 126) / 2
LCM(122,126) = 15372 / 2
LCM(122,126) = 7686
