Question

The H.C.F. and L.C.M. of two numbers are 12 and 5040 respectively. If one of the numbers is 144 find the other number

• A. $420$
• B. $202$
• C. $101$
• D. $111$

Answer 1

Answer: (A)

$420$

Given $HCF=12,LCM=5040$

and also one number is $144$

Let the other number be $x$

As we know that

Product of two numbers is $HCF\times LCM$

$⟹144\times x=12\times 5040$

$⟹x=420$

The other number is $420$
