Problem #126

Playing with constraints

Let x = last 7 non-zero digit of 99 ^ {99}!

Define F(n,k) = Sum of kth powers of all divisors of n, so for example F(6,2) = 1^2 + 2^2 + 3^2 + 6^2 = 50

Define further G(a,b,k) as: Sum of F(j,k) where j varies from a to b both inclusive

You need to enter the value of G(1,x*x,2) modulo (10^9+7)
