Create a function isDivisible(n, x, y) that checks if a number n is divisible by two numbers x AND y. All inputs are positive, non-zero digits.
Example:
isDivisible(3,1,3)--> true because 3 is divisible by 1 and 3
isDivisible(12,2,6)--> true because 12 is divisible by 2 and 6
isDivisible(100,5,3)--> false because 100 is not divisible by 3
isDivisible(12,7,5)--> false because 12 is neither divisible by 7 nor 5
