Comment You don't need that much hardware (Score -1, Offtopic) 95
Each digit is one byte. 105 terabytes is easy enough to get on consumer hardware with 6 spinning rust drives and you only need them for writing - at SATA-III speeds the best spinning rust is ~500MB/s, so ~60 hours to fill up that much data. To calculate, you just need a simple machine that does the 22/7 calculation and has just enough space for holding results to two digits and continuing to divide by 7 each successive iteration on that enough times to keep that bandwidth requirement met.
Leave it to math nerd to not understand what hardware they truly need. 75 days and petabytes of storage when proper thinking and planning and understanding of the basic requirements would have been so much cheaper. They should have used first principles this whole process and obviously failed to do so.
