One method for determining the LCM of 122 and 129 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 129's prime factorization:
3 | 129 |
43 | 43 |
1 |
Prime factors of 129 are 3,43.
129 = 31×431
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, 3,43
.21×31×431×611 = 15738
This shows that the LCM of 122 and 129 is 15738.
The first step in determining the Least Common Multiple of 122 and 129 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 122 and 129:
Lets look at the first ten multiples of these numbers, 122 and 129:
122,244,366,488,610,732,854,976,1098,2074 are the first ten multiples of 122.
129,258,387,516,645,774,903,1032,1161,2193 are the first ten multiples of 129.
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 129, for example, are 1464, 2074, and 2064. 15738 is the least common multiple since it is the smallest.
122 and 129 have an LCM of 15738.
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 122 and 129, than apply into the LCM equation.
GCF(122,129) = 1
LCM(122,129) = ( 122 × 129) / 1
LCM(122,129) = 15738 / 1
LCM(122,129) = 15738
