In this post, we will show you how to use INT and LCM Functions in Microsoft Excel. The **INT** function rounds a number down to the nearest integer. If the number is negative, it will round away from zero. The formula for The INT function is *INT (number)*. The **LCM **function returns the least common multiple of integers. The formula for the LCM function is *LCM (number1, [number2] …). *Both INT and LCM are *Math and Trig* Functions.

### The syntax for Excel INT and LCM Functions

#### INT

**Number**: The number in which you want to round down. The number is required.

#### LCM

**Number1, [number2]**: Number one is required, number two is optional. LCM functions let you find values for the least common factor.
