For all natural numbers ( the counting numbers, 1,2,3,4, are natural numbers), 840 times each of those is a multiple of 840. We say let k be the natural numbers 1,2,3... where ... means it goes on forever. So we have 840k are all the multiples Here is a list of a few. 840 x 1 = 840 840 x 2 = 1680 840 x 3 = 2520 840 x 4 = 3360 we continue with 840x5, 840x6, etc.
