The sum of the numbers of the prime numbers of mersenne

I have a problem to calculate the sum of the digits of the prime numbers of mersenne $ M_ {57885161} $ , $ M_ {74207281} $ , and $ M_ {77232917} $. I'm not a "computer guy" but I know that the sum of the numbers from the computer $ M_ {82589933} $ is $ 111879913. Could you help me? Thank you.
