standard outputToday on a math lesson the teacher told Vovochka that the Euler function of a positive integer φ(*n*) is an arithmetic function that counts the positive integers less than or equal to n that are relatively prime to n. The number 1 is coprime to all the positive integers and φ(1) = 1.

Now the teacher gave Vovochka an array of *n* positive integers *a*_{1}, *a*_{2}, ..., *a*_{n} and a task to process *q* queries *l*_{i} *r*_{i} — to calculate and print modulo 10^{9} + 7. As it is too hard for a second grade school student, you've decided to help Vovochka.

Input

The first line of the input contains number *n* (1 ≤ *n* ≤ 200 000) — the length of the array given to Vovochka. The second line contains *n* integers *a*_{1}, *a*_{2}, ..., *a*_{n} (1 ≤ *a*_{i} ≤ 10^{6}).

The third line contains integer *q* (1 ≤ *q* ≤ 200 000) — the number of queries. Next *q* lines contain the queries, one per line. Each query is defined by the boundaries of the segment *l*_{i} and *r*_{i} (1 ≤ *l*_{i} ≤ *r*_{i} ≤ *n*).

Output

Print *q* numbers — the value of the Euler function for each query, calculated modulo 10^{9} + 7.

Note

In the second sample the values are calculated like that:

- φ(13·52·6) = φ(4056) = 1248
- φ(52·6·10·1) = φ(3120) = 768
- φ(24·63·13·52·6·10·1) = φ(61326720) = 12939264
- φ(63·13·52) = φ(42588) = 11232
- φ(13·52·6·10) = φ(40560) = 9984
- φ(63·13·52·6·10) = φ(2555280) = 539136
