You're incorrect

10×9×8×7×6!/6!=x! 5×2×3×3×4×2×7=x! 5×6×3×4×2×7=7×6×5×4×3×2=7!=x! X=7

U makes math a lot easier thank u

[@brandonhicks7549]

3 seconds tells you it has to be 7!, because the 7 factor is prime and isn’t canceled, and there are only 8 and 10 even factors left(2^4), so not enough factors of two to make it 8!

Great explanation.
