60 and 6. Grandad died at 60?

Real close Wayne but the answer is.....

Answer: Grandfather 66, grandson 6.
Grandfather Grandson
61 1 (61 = 1 x 61)

62 2 (62 = 2 x 31)

63 3 (63 = 3 x 21)

64 4 (64 = 4 x 16)

65 5 (65 = 5 x 13)

66 6 (66 = 6 x 11)

So on the sixth birthday, they are 66 and 6 respectively.
