How about: 2*3*11 = 66
Any prime numbers of about 66 or 67 digits will do.
As a product of its prime factors: 2*3*11 = 66
64 + 66 + 68 = 198

Any prime numbers of about 66 or 67 digits will do.
66 = 2*3*11
As a product of its prime factors: 2*3*11 = 66
64 + 66 + 68 = 198
The three numbers will be 20, 22, and 24. 20 + 22 + 24 = 66
