A) 13
B) 12
C) 14
D) 18
Correct Answer: B
Solution :
Let LCM = 5x, then HCF = x Now, product of numbers = 720 (\[\therefore \]HCF \[\times \] LCM= Product of the numbers) So, here \[(5x)\,\,x=720\] \[\Rightarrow \] \[5{{x}^{2}}=720\] \[\Rightarrow \] \[{{x}^{2}}=144\] \[\therefore \] \[x=12\]You need to login to perform this action.
