What is LCM of 173 and 180

Given Numbers are 173, 180

We can find the LCM of 173, 180 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 173 and 180

Multiples of 173 =173,346,519,692,865,1038,1211,1384,1557,1730,1903,2076,2249,2422,2595,2768,2941,

Multiples of 180 =180,360,540,720,900,1080,1260,1440,1620,1800,1980,2160,2340,2520,2700,2880,3060,

Now, get the least common multiple of 173, 180 which is 31140

So, the LCM of 173, 180 is 31140.

Least Common Multiple (LCM) of 173 and 180 with the help of Prime Factorisation

One method for determining the LCM of 173 and 180 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 173's prime factorization:

173	173
	1

Prime factors of 173 are 173.

173 = 173¹

And this is 180's prime factorization:

2	180
2	90
3	45
3	15
5	5
	1

Prime factors of 180 are 2, 3,5.

180 = 2²×3²×5¹

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:173, 2, 3,5

2²×3²×5¹×173¹ = 31140

This shows that the LCM of 173 and 180 is 31140.

How to Calculate the LCM of 173 and 180 Using Common Multiples

The first step in determining the Least Common Multiple of 173 and 180 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 173 and 180:

Lets look at the first ten multiples of these numbers, 173 and 180:

173,346,519,692,865,1038,1211,1384,1557,2941 are the first ten multiples of 173.

180,360,540,720,900,1080,1260,1440,1620,3060 are the first ten multiples of 180.

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 173 and 180, for example, are 2076, 2941, and 2880. 31140 is the least common multiple since it is the smallest.
