Given Numbers are 340, 345

We can find the LCM of 340, 345 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 340 and 345

Multiples of 340 =340,680,1020,1360,1700,2040,2380,2720,3060,3400,3740,4080,4420,4760,5100,5440,5780,

Multiples of 345 =345,690,1035,1380,1725,2070,2415,2760,3105,3450,3795,4140,4485,4830,5175,5520,5865,

Now, get the least common multiple of 340, 345 which is 23460

So, the LCM of 340, 345 is 23460.

One method for determining the LCM of 340 and 345 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 340's prime factorization:

Prime factors of 340 are 2, 5,17.

340 = 2²×5¹×17¹

And this is 345's prime factorization:

Prime factors of 345 are 3, 5,23.

345 = 3¹×5¹×23¹

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: 2, 5,17, 3,23

2²×3¹×5¹×17¹×23¹ = 23460

This shows that the LCM of 340 and 345 is 23460.

The first step in determining the Least Common Multiple of 340 and 345 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 340 and 345:

Lets look at the first ten multiples of these numbers, 340 and 345:

340,680,1020,1360,1700,2040,2380,2720,3060,5780 are the first ten multiples of 340.

345,690,1035,1380,1725,2070,2415,2760,3105,5865 are the first ten multiples of 345.

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 340 and 345, for example, are 4080, 5780, and 5520. 23460 is the least common multiple since it is the smallest.

340 and 345 have an LCM of 23460.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 340 and 345, than apply into the LCM equation.

GCF(340,345) = 5
LCM(340,345) = ( 340 × 345) / 5
LCM(340,345) = 117300 / 5
LCM(340,345) = 23460
