Question

the hcf of two numbers is 12 and their product is 4320 what is their lcm?if one number is 60 what is the other number

Answer 1

LCM *HCF = Product of numbers
=> LCM *12 = 4320
=> LCM = 360

First no. = 60
Product of numbers = 4320

Second No. = Product of numbers / First no.
Second No. = 4320/60
= 72

Answer 2

Hey

Given that :-

HCF = 12

Product of two numbers = 4320

To find :-

• LCM
• Second number .

Now , we know that ,

LCM * HCF = Product of two numbers

=> LCM * 12 = 4320

=> LCM = 4320 / 12

=> LCM = 360

So ,

LCM = 360 .

Now first number = 60

Second number = ??

So ,

a * b = 4320

=> 60 * b = 4320

=> b = 4320 / 60

=> b = 72

So , second number = 72


thanks :)
