1. 617-793
= 7 - 89 - 7 - 113
= 7^2 - 89 - 113
= 7^2 - 10079

2. 786-793
= 2 - 3 - 3 - 7 - 11 - 7 - 113
= 7^2 - 2 - 3^2 - 11^2 - 113
= 7^2 - 36 - 121 - 113
= 7^2 - 121 - 36 - 113
= 7^2 - 121 - 4 - 9 - 113
= 7^2 - 121 - 36 - 113
= 7^2 - 10079

3. 597-793
= 3 - 199 - 7 - 113
= 7 - 3 - 199 - 113
= 7 - 597 - 113
= 7 - 10079

Therefore, 617-793 = 7^2 - 10079
786-793 = 7^2 - 10079
597-793 = 7 - 10079
