So, the LCM of 143, 149 is 21307.

One method for determining the LCM of 143 and 149 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 143's prime factorization:

Prime factors of 143 are 11,13.

143 = 11¹×13¹

And this is 149's prime factorization:

Prime factors of 149 are 149.

149 = 149¹

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: 11,13,149

11¹×13¹×149¹ = 21307

This shows that the LCM of 143 and 149 is 21307.

The first step in determining the Least Common Multiple of 143 and 149 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 143 and 149:

Lets look at the first ten multiples of these numbers, 143 and 149:

143,286,429,572,715,858,1001,1144,1287,2431 are the first ten multiples of 143.

149,298,447,596,745,894,1043,1192,1341,2533 are the first ten multiples of 149.

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 143 and 149, for example, are 1716, 2431, and 2384. 21307 is the least common multiple since it is the smallest.

143 and 149 have an LCM of 21307.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 143 and 149, than apply into the LCM equation.

GCF(143,149) = 1
LCM(143,149) = ( 143 × 149) / 1
LCM(143,149) = 21307 / 1
LCM(143,149) = 21307
