Given Numbers are 121, 126

We can find the LCM of 121, 126 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 121 and 126

Multiples of 121 =121,242,363,484,605,726,847,968,1089,1210,1331,1452,1573,1694,1815,1936,2057,

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 121, 126 which is 15246

So, the LCM of 121, 126 is 15246.

One method for determining the LCM of 121 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 121's prime factorization:

Prime factors of 121 are 11.

121 = 11²

And this is 126's prime factorization:

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:11, 2, 3,7

2¹×3²×7¹×11² = 15246

This shows that the LCM of 121 and 126 is 15246.

The first step in determining the Least Common Multiple of 121 and 126 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 121 and 126:

Lets look at the first ten multiples of these numbers, 121 and 126:

121,242,363,484,605,726,847,968,1089,2057 are the first ten multiples of 121.

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 121 and 126, for example, are 1452, 2057, and 2016. 15246 is the least common multiple since it is the smallest.

121 and 126 have an LCM of 15246.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 121 and 126, than apply into the LCM equation.

GCF(121,126) = 1
LCM(121,126) = ( 121 × 126) / 1
LCM(121,126) = 15246 / 1
LCM(121,126) = 15246
