The HCF of two numbers is 11 and their LCM is 693. If one of the numbers is 77 find the other.

Correct option is B

Given:
HCF = 11
LCM = 693
One of the numbers = 77
Formula Used:
HCF × LCM = Product of the two numbers
Solution:
Let the other number be x.
77 × x = 11 × 693
x = $$\frac {(11 × 693)}{ 77}$$​= 99
The other number is 99.
