We find an upper bound for the norm of the matrix whose entry is , where and are the greatest common divisor and the least common multiple of and and where and are real numbers. In fact, we show that if and , then for all positive integers , where is the Riemann zeta function.

  • Real Number
  • Zeta Function
  • Great Common Divisor
  • Riemann Zeta Function
