Question 55
If LCM of two numbers is 231, HCF of two numbers is 11 and one number is 77, the other number is:
Solution
As we know that $$one\ number\ \times\ other\ number\ =\ LCM\times\ HCF$$
If LCM of two numbers is 231, HCF of two numbers is 11 and one number is 77.
$$77\ \times\ other\ number\ =\ 231\times\ 11$$
$$7\ \times\ other\ number\ = 231$$
other number = 33
