A really handy way to multiply all values of an Iterable or range is to use reduce:

val m = (1..4).reduce { accumulator, element ->
    accumulator * element
}

println(m)

This would print:

24

The accumulator is initially the first value of the range. This will be multiplied with the next element and becomes the accumulator for the next run.
