Question

If hcf (a, 8) =4 and Lcm (a, 8) =24then a is

Answer 1

HCF(a, 8) = 4

LCM(a, 8) = 24

We know,

==> HCF × LCM = product of numbers

==> 4 × 24 = 8 × a

==> 4 × 3 = a

==> a = 12

∴ value of a = 12

Answer 2

Given  :  HCF  =4

              LCM  = 24

             Product of two number = a  ,   8

find the value of 'a'

using the value of  'product of two number = product of HCF X LCM

== a x 8 = 4 x 24

==8a = 96

==a = 96/8

==a = 12

Hence , the value of 'a'= 12
