Every nonzero number has multiples. Every set of nonzero numbers has an LCM.
Multiply a given number by successive counting numbers.
Take the first number. Add it to itself. Keep adding that number to the total three more times. The first five nonzero multiples of 9 are 9, 18, 27, 36, and 45. Put another way, let each number equal x. The first five nonzero multiples of x are 1x, 2x, 3x, 4x and 5x.
40, 80, 120, 160, 200
The first five nonzero multiples of 6 are 6, 12, 18, 24 and 30.
The first few multiples of nineteen are:1938577695114133152171190209
