**RESULT**

LCM(**75**, **20**) = **300**

**DESCRIPTIONS**

Prime factorization of 75 :

(**75** = **3** × **5** × **5**)

Prime factorization of 20 :

(**20** = **2** × **2** × **5**)

- 75 =
**3**××__5__**5** - 20 =
**2**×**2**×__5__

Provided that the common prime factor (** 5**) appears in the multiplication only once, the LCM of 75 and 20 is equal to the product of all prime factors.

LCM(**75**, **20**) = **5** × **3** × **5** × **2** × **2** = **300**
