If the sum is too large, you can repeat the process until you can tell whether it is a multiple of three. This is the basis for the solution. Since the last two digits are 23, the sum of the digits is 2+3=5 (therefore it is not divisible by three). However certain numbers can...
Subsets of {2,3,4,5,6,7,8,9} indude a singe digit up to all eigh tnumbers.Therefore,we must add the combinations of all possible subsets and subtract from each of the subsets fomed by the composite numbers. Hence: (81)−(41)+(82)−(42)+(83)−(43)+(84)−1+(85)...
