Problem Statement

For the several values of the parameter mNm\in \mathbb{N^{*}},find the pairs of integers (a,b)(a,b) that satisfy the relation
                                                        [a,m]+[b,m](a+b)m=1011\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \frac{[a,m]+[b,m]}{(a+b)m}=\frac{10}{11},
and,moreover,on the Cartesian plane OxyOxy the lie in the square D={(x,y):1x36,1y36}D=\{(x,y):1\leq x\leq 36,1\leq y\leq 36\}.
Note:[k,l][k,l] denotes the least common multiple of the positive integers k,lk,l.
