Question

LCM of two numbers is 2079 and HCF is 81. If one of the number is 99, find the other number
​

Answer 1

Step-by-step explanation:

a * b = LCM * HCF

b = LCM * HCF / a

b = 2079 * 81 / 99

b = 2079 * 9 / 11

b = 189 * 9

b = 1701

Answer 2

Answer:

1701

Step-by-step explanation:

we know that

HCF×LCM = product of 2 no.s

let unknown no. be x

2079×81 = 99x

x= 2079×81/99

= 2079×9/11

=189×9

=1701

BTW., this situation isn't possible since 81 is not factor of 99 and hence cannot be HCF
