What is LCM of 338 and 342

Given Numbers are 338, 342

We can find the LCM of 338, 342 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 338 and 342

Multiples of 338 =338,676,1014,1352,1690,2028,2366,2704,3042,3380,3718,4056,4394,4732,5070,5408,5746,

Multiples of 342 =342,684,1026,1368,1710,2052,2394,2736,3078,3420,3762,4104,4446,4788,5130,5472,5814,

Now, get the least common multiple of 338, 342 which is 57798

So, the LCM of 338, 342 is 57798.

Least Common Multiple (LCM) of 338 and 342 with the help of Prime Factorisation

One method for determining the LCM of 338 and 342 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 338's prime factorization:


2 338
13 169
13 13
1

Prime factors of 338 are 2,13.

338 = 21×132

And this is 342's prime factorization:


2 342
3 171
3 57
19 19
1

Prime factors of 342 are 2, 3,19.

342 = 21×32×191

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: 2,13, 3,19

.

21×32×132×191 = 57798

This shows that the LCM of 338 and 342 is 57798.

How to Calculate the LCM of 338 and 342 Using Common Multiples
