AI Thread Summary
The discussion revolves around solving the equation 28 = -27 (mod m) to find three positive integers greater than 1. The initial approach mistakenly used -17 instead of the correct value of -27. After correcting the error, the user seeks clarification on whether m can be 55, 11, or 5, as these numbers divide 55. The conversation highlights the importance of accurate calculations in modular arithmetic. Ultimately, the focus remains on identifying valid values for m that satisfy the equation.

Homework Statement


a question from a test in discrete math:
find 3 positive numbers that are larger than 1, that 28=-17(mod m)




Homework Equations


which is 28 + 17/m = t
so its 55/m = t
can i say that m= 55,11,5 because they devise 55?

thanks

Oh sry my bad! it was -27 and not -17 lol, so yea: 28= -27(mod m)

Thanks! :)
