**RESULT**

LCM(**16**, **40**) = **80**

**DESCRIPTIONS**

Prime factorization of 16 :

(**16** = **2** × **2** × **2** × **2**)

Prime factorization of 40 :

(**40** = **2** × **2** × **2** × **5**)

- 16 =
×__2__×__2__×__2__**2** - 40 =
×__2__×__2__×__2__**5**

Provided that the common prime factors (**2**, **2** and **2**) appear in the multiplication only once, the LCM of 16 and 40 is equal to the product of all prime factors.

LCM(**16**, **40**) = **2** × **2** × **2** × **2** × **5** = **80**
