Answer 1

Answer:

rgv yuva yuddh yuhgb yogi

Answer 2

Answer:

1260

Step-by-step explanation:

we must find the lcm of List all prime factors for each number.

Prime Factorization of 12 is:

2 x 2 x 3  =>  22 x 31

Prime Factorization of 18 is:

2 x 3 x 3  =>  21 x 32

Prime Factorization of 20 is:

2 x 2 x 5  =>  22 x 51

Prime Factorization of 21 is:

3 x 7  =>  31 x 71  

Prime Factorization of 28 is:

2 x 2 x 7  =>  22 x 71  

Prime Factorization of 30 is:

2 x 3 x 5  =>  21 x 31 x 51

The new superset list is

2, 2, 3, 3, 5, 7

Multiply these factors together to find the LCM.  

LCM = 2 x 2 x 3 x 3 x 5 x 7 = 1260
