So, the LCM of 139, 143 is 19877.

One method for determining the LCM of 139 and 143 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 139's prime factorization:

Prime factors of 139 are 139.

139 = 139¹

And this is 143's prime factorization:

Prime factors of 143 are 11,13.

143 = 11¹×13¹

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:139, 11,13

11¹×13¹×139¹ = 19877

This shows that the LCM of 139 and 143 is 19877.

The first step in determining the Least Common Multiple of 139 and 143 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 139 and 143:

Lets look at the first ten multiples of these numbers, 139 and 143:

139,278,417,556,695,834,973,1112,1251,2363 are the first ten multiples of 139.

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

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 139 and 143, for example, are 1668, 2363, and 2288. 19877 is the least common multiple since it is the smallest.

139 and 143 have an LCM of 19877.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 139 and 143, than apply into the LCM equation.

GCF(139,143) = 1
LCM(139,143) = ( 139 × 143) / 1
LCM(139,143) = 19877 / 1
LCM(139,143) = 19877
