Description
Let's introduce some definitions that will be needed later.
Let prime(x) be the set of prime divisors of x. For example, prime(140)={2,5,7}, prime(169)={13}.
Let g(x,p) be the maximum possible integer pk where k is an integer such that x is divisible by pk. For example:
- g(45,3)=9 (45 is divisible by 32=9 but not divisible by 33=27),
- g(63,7)=7 (63 is divisible by 71=7 but not divisible by 72=49).
Let f(x,y) be the product of g(y,p) for all p in prime(x). For example:
- f(30,70)=g(70,2)⋅g(70,3)⋅g(70,5)=21⋅30⋅51=10,
- f(525,63)=g(63,3)⋅g(63,5)⋅g(63,7)=32⋅50⋅71=63.
You have integers x and n. Calculate f(x,1)⋅f(x,2)⋅…⋅f(x,n)mod(109+7).
The only line contains integers x and n (2≤x≤109, 1≤n≤1018) — the numbers used in formula.
The only line contains integers x and n (2≤x≤109, 1≤n≤1018) — the numbers used in formula.
Output
Print the answer.
Samples
Note
In the first example, f(10,1)=g(1,2)⋅g(1,5)=1, f(10,2)=g(2,2)⋅g(2,5)=2.
In the second example, actual value of formula is approximately 1.597⋅10171. Make sure you print the answer modulo (109+7).
In the third example, be careful about overflow issue.
