Question

LCM of 8,69, 9,19,12​

Answer 1

Answer:

31,464

Step-by-step explanation:

List all prime factors for each number.

Prime Factorization of 8 is:

2 x 2 x 2  =>  23

Prime Factorization of 9 is:

3 x 3  =>  32

Prime Factorization of 12 is:

2 x 2 x 3  =>  22 x 31

Prime Factorization of 19 shows:

19 is prime  =>  191

Prime Factorization of 69 is:

3 x 23  =>  31 x 231

For each prime factor, find where it occurs most often as a factor and write it that many times in a new list.

The new superset list is

2, 2, 2, 3, 3, 19, 23

Multiply these factors together to find the LCM.

LCM = 2 x 2 x 2 x 3 x 3 x 19 x 23 = 31464

In exponential form:

LCM = 23 x 32 x 191 x 231 = 31464

LCM = 31464

Therefore,

LCM(8, 9, 12, 19, 69) = 31,464

Hope this helps you dear !!
