Prime Factors of Double Integer Value

f = factor(200)
f =

     2     2     2     5     5

Multiply the elements of f to reproduce the input value.

prod(f)
ans =

   200

Prime Factors of Unsigned Integer Value

n = uint16(138);
f = factor(n)
f =

       2      3     23

Multiply the elements of f to reproduce n.

prod(f)
ans =

   138
