**RESULT**

LCM(**72**, **90**) = **360**

**DESCRIPTIONS**

Prime factorization of 72 :

(**72** = **2** × **2** × **2** × **3** × **3**)

Prime factorization of 90 :

(**90** = **2** × **3** × **3** × **5**)

- 72 =
×__2__**2**×**2**××__3____3__ - 90 =
×__2__×__3__×__3__**5**

Provided that the common prime factors (**2**, **3** and **3**) appear in the multiplication only once, the LCM of 72 and 90 is equal to the product of all prime factors.

LCM(**72**, **90**) = **2** × **3** × **3** × **2** × **2** × **5** = **360**
