Don't forget that 0 is a multiple of every number. The problem now is whether your teacher uses 0 as the first multiple of a number or starts with the number itself as the first multiple. If you use 0 as the first multiple, then you have...
0, 100, 200...
0, 10, 20, 30, 40, 50...
0, 4, 8, 12, 16, 20, 24, 28,...
200+50+28=278 as compared to 392
