  +# A positive integer is magical if it is divisible by either A or B.
  +#
  +# Return the N-th magical number.
  +# Since the answer may be very large, return it modulo 10^9 + 7.
  +#
  +# Example 1:
  +#
  +# Input: N = 1, A = 2, B = 3
  +# Output: 2
  +# Example 2:
  +#
  +# Input: N = 4, A = 2, B = 3
  +# Output: 6
  +# Example 3:
  +#
  +# Input: N = 5, A = 2, B = 4
  +# Output: 10
  +# Example 4:
  +#
  +# Input: N = 3, A = 6, B = 4
  +# Output: 8
  +#
  +# Note:
  +# - 1 <= N <= 10^9
  +# - 2 <= A <= 40000
  +# - 2 <= B <= 40000
