# LCM

Returns the least common multiple of integers. The least common multiple is the smallest positive integer that is a multiple of all integer arguments number1, number2, and so on. Use LCM to add fractions with different denominators.

## Syntax

LCM(number1, [number2], ...)


### Parameters

Term Definition
number1, number2,... Number1 is required, subsequent numbers are optional. 1 to 255 values for which you want the least common multiple. If value is not an integer, it is truncated.

## Return value

Returns the least common multiple of integers.

## Remarks

• If any argument is nonnumeric, LCM returns the #VALUE! error value.

• If any argument is less than zero, LCM returns the #NUM! error value.

• If LCM(a,b) >=2^53, LCM returns the #NUM! error value.

• This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.

## Example

Formula Description Result
= LCM(5, 2) Least common multiple of 5 and 2. 10
