The last birthday the grandson was 6
and the grandfather was 66.
The six consecutive-multiple birthday ages:
Grandfather:  61,  62,  63,  64,  65,  66
Grandson...:   1,   2,   3,   4,   5,   6

A theoretical possibility, though the official oldest age has been only 122 years (Jeanne Calment, d. 1997), is...
the last birthday the grandson was 6
and the grandfather was 126.
The six consecutive-multiple birthday ages:
Grandfather: 121, 122, 123, 124, 125, 126
Grandson...:   1,   2,   3,   4,   5,   6
