LCM and HCF of two numbers are 144 and 8 respectively. If one of the numbers is 16, then find the other number.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 72.
Given: LCM = 144, HCF = 8, one number = 16
LCM × HCF = Product of two numbers
So, 144 × 8 = 16 × x
⇒ 1152 = 16x
⇒ x = 1152 ÷ 16 = 72
