Determine the smallest positive integer which is 2 times a square, 3 times a cube, 5 times a fifth power, 7 times a seventh power, and 11 times an eleventh power.
For example, 648 is 2 times the square of 18, and 3 times the cube of 6.

You are correct, I neglected the effect of, for example, the multiple 7's affecting whether the rest after one seven, was a square.
And my arithmetic error was the result of including 7*330 instead of 7^330 in the calculation of what was an erroneous formula anyway.
