Correct answer: B
We know that for any two numbers, the product of the numbers is equal to the product of their HCF and LCM.
Let the other number be x.
Therefore, 117 * x = HCF * LCM.
Substituting the given values: 117 * x = 13 * 1989.
Solving for x: x = (13 * 1989) / 117.
Calculating the value: x = 25857 / 117 = 221.
Thus, the other number is 221.
