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
