For a positive integer x, F(x) indicates the number of kind of prime factor of x. For example F(2)\u003d1. F(10)\u003d2, because 10\u003d2*5. F(12)\u003d2, because 12\u003d2*2*3, there are two kinds of prime factor. For each query, we will get an interval [L, R], Hdu wants to know $\\max GCD(F(i),F(j))$ $(L\\leq i\u0026lt;j\\leq R) $\u003c/div\u003e"}},{"title":"Input","value":{"format":"HTML","content":"There are multiple queries.
