LCM and HCF of two numbers are 198 and 33, respectively. If one of the numbers is 99, then find the other number.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 66.
LCM = 198, HCF = 33
One number = 99
Find the other number
Number1 × Number2 = HCF × LCM
Let the other number = x
99 × x = 33 × 198
33 × 198 = 33 × (2 × 99)
= 33 × 2 × 99 = 66 × 99
99 × x = 66 × 99 → x = 66
