Ques. The ratio of two numbers is 3:4 and their HCF is 4.Their LCM is: Op 1: 12 Op 2: 16
Op 3: 24 Op 4: 48

• let the no.s be 3x, 4x
  hcf=4(given)
  hcf of 3x and 4x is x
  therefore, x=4
  no.s are=3*4,4*4
  =12,16
  lcm=product of no.s/hcf
  =(12*16)/4
  =48

• 48
  As the HCF is 4 so number will be 12 & 16 and thus LCM of 12,16 is 48

• x1/x2=34=p that means x1=3p,x2=4p and
  HCF(3P,4P)=P and p=4(GIVEN) so numbers x1=12 and x2=16
  so, X1*X2=HCF*LCM, 12*16=4*LCM
  LCM=48

• no ratio r 3:4 and hcf=4
  then no=3*4=12
  and 4*4=16
  hence lcm of 12,16 is 48

• 4: 48
  
  If numbers are 3x & 4x and their LCM=y, then 3x*4x=LCM*HCF, 12x^2=4y or 3x^2=y
  As the HCF=4, So these numbers must be multiple of 4,So numbers are 12,16 so x=4 and
  LCM=y=3*4^2=48

• We assume Two numbers are 3x and 4x then HCF of two numbers is x.
  The given HCF=4 =>x=4
  Product of two numbers =HCFxLCM
  12x16=4xLCM
  =>LCM=48

• given a=3 and b=4
  therefor,a*HCF*b*HCF= HCF*LCM
  =>3*4*4*4 =4*LCM =>LCM=3*4*4*4/4=48

• let the numbers be 3x and 4x.
  hcf of 3x and 4x = x.
  but, hcf=4(given).
  so, x=4.
  so by formula of hcf*lcm=one no.* other no.
  4*lcm=12*16
  gives lcm=48.
  so answer is 48. (Op 4.)
