LCM and HCF of two numbers are 198 and 9 respectively. If one of the numbers is 99, then find the other number.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 18.
Given:
LCM = 198
HCF = 9
One number = 99
Let other number = x
Product of two numbers = LCM × HCF
⇒ 99 × x = 198 × 9
⇒ 99x = 1782
⇒ x = 1782 ÷ 99 = 18
