### lcm()

# lcm()

lcm(expr0,expr1) ⇒ number

Both expr0 and expr1 must be integer values.

The lcm() function returns the least common multiple of the two arguments as a number.

The least common multiple of two integers

*a*and*b*is the smallest positive integer that is divisible by both*a*and*b*.If

*a*and/or*b*are note integers, the function gives unexpected results. For example lcm(2.5,5) gives 12.5, but obviously 12.5 is not a multiple of 5.Use the calculator at the top right to find the least common multiple of two (or more) integers.
