Question

LCM of two numbers is 72 and their HCF is 9.if one of the number is 12 than the other number is

Answer 1

Answer:

54

Step-by-step explanation:

lcm× hcf=one number×other number

72×9=12×other number

other number=(72×9)/12

=54

Answer 2

The other number is 12.

Given:

LCM of two numbers is 72

HCF of the two numbers is 9

One of the numbers is 12

To Find;

The other number

Solution:

We know the relation between LCM, HCF and the two numbers as

$LCM*HCF=a*b$

where a and b are the two numbers.

Hence here we have a = 12. Therefore

$72*9 = 12b\\b=54$

The other number is 54. Though this is not possible as neither 72 is a multiple of 54 nor 9 is a factor of 12.
