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
Read Solution (Total 8)
-
- 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 - 9 years agoHelpfull: Yes(2) No(1)
- 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 - 9 years agoHelpfull: Yes(1) No(0)
- no ratio r 3:4 and hcf=4
then no=3*4=12
and 4*4=16
hence lcm of 12,16 is 48 - 9 years agoHelpfull: Yes(1) No(0)
- 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 - 9 years agoHelpfull: Yes(0) No(0)
- 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 - 9 years agoHelpfull: Yes(0) No(0)
- 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 - 7 years agoHelpfull: Yes(0) No(0)
- 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.) - 7 years agoHelpfull: Yes(0) No(0)
