Airport has m runways of length n units.

The rules of game are as follows:

• One can start at any runway.

• One can switch from ith runway to jth runway if (i, j) are coprime.

• It is compulsory to switch between runway after every 1 unit.

• One has to reach end of runway.

Find number of ways in which this can be achieved. As answer could be large, print it modulo 1000000007.

1<=n<=1000000000

1<=m<=10

Plz help me in this question.
