Step-by-step explanation:

Prime Factorization of 18 is:

2 x 3 x 3 => 21 x 32

Prime Factorization of 25 is:

5 x 5 => 52

Prime Factorization of 30 is:

2 x 3 x 5 => 21 x 31 x 51

Prime Factorization of 60 is:

2 x 2 x 3 x 5 => 22 x 31 x 51

So,

The prime factors are

2, 2, 3, 3, 5, 5

LCM = 2 x 2 x 3 x 3 x 5 x 5 = 900

Therefore,

LCM(18, 25, 30, 60) = 900
