The total number of integers that are multiples of both 56 and 84 is infinite. Here are the first few: 168, 336, 504, 672, 840, 1008 . . .
If you are counting by 8, the numbers you will say are those that are multiples of 8. Among the numbers 32, 56, 72, and 84, all of them are multiples of 8 except for 84, which is not a multiple of 8. Therefore, the number you will not say is 84.
The first five common multiples of 4 and 7 is 28, 56, 84, 112, 140.28, 56, 84, 112, 14028 56 84 112 140
