So, the LCM of 155, 163 is 25265.

One method for determining the LCM of 155 and 163 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 155's prime factorization:

Prime factors of 155 are 5,31.

155 = 5¹×31¹

And this is 163's prime factorization:

Prime factors of 163 are 163.

163 = 163¹

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: 5,31,163

5¹×31¹×163¹ = 25265

This shows that the LCM of 155 and 163 is 25265.

The first step in determining the Least Common Multiple of 155 and 163 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 155 and 163:

Lets look at the first ten multiples of these numbers, 155 and 163:

155,310,465,620,775,930,1085,1240,1395,2635 are the first ten multiples of 155.

163,326,489,652,815,978,1141,1304,1467,2771 are the first ten multiples of 163.

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 155 and 163, for example, are 1860, 2635, and 2608. 25265 is the least common multiple since it is the smallest.

155 and 163 have an LCM of 25265.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 155 and 163, than apply into the LCM equation.

GCF(155,163) = 1
LCM(155,163) = ( 155 × 163) / 1
LCM(155,163) = 25265 / 1
LCM(155,163) = 25265
