Question

The HCF of two numbers is 12 and their LCM is 360. If one number is 60, then the other number is ___.

• A. 72
• B. 60
• C. 48
• D. 96

Answer 1

The correct option is A

72

One number = 60
Other number = ?
LCM = 360
HCF = 12
Product of two numbers = product of HCF and LCM
$60\times ?=360\times 12?=\frac{\text{Product of HCF and LCM}}{\text{First number}}?=\frac{\text{/}{360}^6\times 12}{\text{/}{60}_1}=72$
