You have converted an inexact floating-point number to exact form.  The precision was lost before x: was applied.

OK, so I need to use extended integers when I use the prime factors

 verb q:

If the right argument of q: is not extended:

__ q: 55340232221128654853

2 3

64 1

The extended product of the resulting factors is wrong:

(2x^64)*3x

55340232221128654848

<<<>>>

If the right argument of q: is extended:

__ q: 55340232221128654853x

23 79 7561 155251 25946119

1 1 1 1 1

Extended product of the resulting factors is correct:

*/23 79 7561 155251 25946119x

55340232221128654853
