1.

the lcm of two numbers is 567 and their hcf is 9 if the difference the two numbers is 18 find the two numbers

Answer»

answer is : a=81 and b=63


use LCM*HCF=a*b

where a and b are the two nos.


By this U will arrive to an eqn b^2+18b-5103=0

Solve this equation


b is obtained as EITHER -81 or 63

ignore the -ve VALUE.


USING the +ve value of b we arrive at a. (using |a-b| = 18)
