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.
