Exclamation I really don't know. Please, help

1) Prove that if the positive integers a,b,c,d satisfy the equation a^2+b^2+c^2+d^2=2018! each of the numbers a,b,c,d is greater than 10^250

2) 2n players participated in the tennis tournament, where n> = 15 is an integer. Each pair of players played exactly one match. There were no draws. When for each player was counted, with how many players he won, it turned out that no five players did not get the same result. Show that players can be divided into groups A and B, each consisting of n players, that among the matches between players from group A and players from group B, what is more, 60% was won by players from group A

I would be really grateful for help

Help implies you present your work thus far and explain where you are stuck or ask questions. So far all you have done is copied down your homework. I'm not sure how to "help".
