Hi again,

I have been able to do mod questions such as:

.45 Ξ 3 (mod 6) and 104 Ξ 2 (mod 6)

45 - 3 = 42

42 / 6 = 7 therefore 45 less 3 (42) is a multiple of 6

104 - 2 = 102

102 / 6 = 17 therefore 104 less 2 (102) is a multiple of 6

I am now asked to do a question with a massive number that a calculator can't do.

Verify 675³⁰⁷ mod 713.

How is this done???
