data = Table[Sqrt[n!], {n, 1, 10}];

sp = data /. Sqrt[_] -> 1

{1,1,1,2,2,12,12,24,72,720}

sfp = data/sp /. Sqrt[x_] -> x

{1,2,6,6,30,5,35,70,70,7}

Dear Mathematica Gurus,
Who know which Matrhematica function uses to separate square free part 
of number.
e.g.
In[1]: Table[Sqrt[n!], {n, 1, 10}]
Out[1]: {1, Sqrt[2], Sqrt[6], 2 Sqrt[6], 2 Sqrt[30], 12 Sqrt[5], 12 
Sqrt[35],
 24 Sqrt[70], 72 Sqrt[70], 720 Sqrt[7]}
What to do to take squre-free parts:
{1, 2, 6, 6, 30, 5, 35, 70, 70, 7}
or square parts
{1, 1, 1, 2, 2, 12, 12, 24, 72, 720}
Best wishes
Artur
