Given Numbers are 163, 170

We can find the LCM of 163, 170 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 163 and 170

Multiples of 163 =163,326,489,652,815,978,1141,1304,1467,1630,1793,1956,2119,2282,2445,2608,2771,

Multiples of 170 =170,340,510,680,850,1020,1190,1360,1530,1700,1870,2040,2210,2380,2550,2720,2890,

Now, get the least common multiple of 163, 170 which is 27710

So, the LCM of 163, 170 is 27710.

One method for determining the LCM of 163 and 170 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 163's prime factorization:

Prime factors of 163 are 163.

163 = 163¹

And this is 170's prime factorization:

Prime factors of 170 are 2, 5,17.

170 = 2¹×5¹×17¹

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:163, 2, 5,17

2¹×5¹×17¹×163¹ = 27710

This shows that the LCM of 163 and 170 is 27710.

The first step in determining the Least Common Multiple of 163 and 170 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 163 and 170:

Lets look at the first ten multiples of these numbers, 163 and 170:

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

170,340,510,680,850,1020,1190,1360,1530,2890 are the first ten multiples of 170.

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 163 and 170, for example, are 1956, 2771, and 2720. 27710 is the least common multiple since it is the smallest.

163 and 170 have an LCM of 27710.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 163 and 170, than apply into the LCM equation.

GCF(163,170) = 1
LCM(163,170) = ( 163 × 170) / 1
LCM(163,170) = 27710 / 1
LCM(163,170) = 27710
