LCM

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

Returns the least common multiple of two or more numbers.

number1	The first number
number2	(Optional) The second number.

REMARKS

* This function returns the smallest positive integer that is a multiple of all the numbers.
* This function returns the smallest positive [[Multiple]] of all the numbers.
* If any of the numbers are not whole numbers (or integers), then they are truncated.
* If any of the arguments are less than zero (negative), then #NUM! is returned.
* If any of the arguments are more than 2^53, then #NUM! is returned.
* If any of the arguments are not numeric, then #VALUE! is returned.
* If the least common multiple is more than 2^53, then #NUM! is returned.
* This function can be used to add fractions with different denominators. (Example 12)
* You can have a maximum of 255 arguments.
* You can use the GCD function to return the greatest common divisor of two or more numbers.
