The LCM of x and y is 441 and their HCF is 7. If x = 49 then find y.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 63.
Given that
The LCM of x and y is 441 and their HCF is 7.
If x = 49
Formula used
LCM × HCF = x × y
Calculation
⇒ 441 × 7 = 49 × y
⇒ y = 441/7 = 63
