Multiplication of two number a,b is 100, and their LCM in 25 then what is HCF of a and b?

• observe that lcm*hcf=product of two numbers is not valid here.Because multiplication of two numbers to get 100 is possible in one of the ways
  1*100,25*4,50*2,10*10 in each ways we will not get lcm as 25. So Question is wrong
• 10 years agoHelpfull: Yes(17) No(6)
• 100/25 = 4
  hcf = 4
• 10 years agoHelpfull: Yes(15) No(3)
• Its a kind of dummy question....there are no such numbers whose product is 100,lcm is 25 and hcf as 4 together
• 10 years agoHelpfull: Yes(12) No(2)
• its of course a dummy question so better dont answer it... though by formula product of number = hcf * lcm
  hcf is 4
  though ne combination dont gve lcm as 25

• lcm*hcf=a*b
  25*x=100
  hcf=4
• 10 years agoHelpfull: Yes(2) No(2)
• HCF×LCM= product of two numbers so therefore
  Hcf×25=100 so HCF=4
• 10 years agoHelpfull: Yes(1) No(3)
• 4
  lcm*hcf=a*b
• 10 years agoHelpfull: Yes(0) No(2)
• 100=HCF*25
  =>HCF=4
• 10 years agoHelpfull: Yes(0) No(1)
• product of a and b= HCF*LCM
  100=25*HCF
  therefore, HCF=4
• 10 years agoHelpfull: Yes(0) No(2)
• hcf*lcm=a*b
  25*hcf=100
  hcf=4
  
• 10 years agoHelpfull: Yes(0) No(2)
• hcfxlcm=product of nos
  hcfx25=100
  hcf=4 ans
  
• 10 years agoHelpfull: Yes(0) No(1)
• lcm * hcf = a* b
  100 = 25 * hcf
  hcf= 4
• 10 years agoHelpfull: Yes(0) No(1)
• ans:4,product of two numbers=product of hcf and lcm so 100=x*25
• 10 years agoHelpfull: Yes(0) No(2)
• lcm(a,b)*hcf(a,b)=a*b
  25*hcf(a,b)=100
  hcf(a,b)=4
• 10 years agoHelpfull: Yes(0) No(1)
• product of two no. (a*b)=product of lcm and hcf
  100 =25*hcf
  hcf=100/25=4
  ans 4
  
  
• 10 years agoHelpfull: Yes(0) No(1)
• hcf= 100/25= 4 ans
  but is it possible ,
  multiple of 100= (10,10), (5,20)
  but where is the hcf 4??
  i think question is wrong
• 10 years agoHelpfull: Yes(0) No(0)
• Hcf = product of numbers÷lcm
  so
  hcf = 100% 25 = 4
• 10 years agoHelpfull: Yes(0) No(0)
• here the question is inconsistent .suppose number 1 -6 ,number 2- 9 .
  HCF of those 2 numbers is 3. &LCM of those 2 numbers is 18 . look that HCF SHOULD BE A FACTOR OF LCM
• 10 years agoHelpfull: Yes(0) No(0)
• Let the two nos be a and b
  Lcm×HCF=a×b(formula)
  25×HCF=100
  HCF=100/25=4
  HCF=4
• 10 years agoHelpfull: Yes(0) No(0)
• ans 4,
  lcm*hcf=products of two no.
• 10 years agoHelpfull: Yes(0) No(0)
• hcf * lcm=product of two no.
  lcm =25
  so, 25*hcf=100
  hcf=4
  
  
• 10 years agoHelpfull: Yes(0) No(0)
• ans 4.
  25*x=100
  x=4
• 10 years agoHelpfull: Yes(0) No(0)
• a*b=Lcm(a,b)*hcf(a,b)
  100=24*cf(a,b)
  hcf= 4

• It is just a dummy Question, whatever you choose option............ you are always wrong.
• 10 years agoHelpfull: Yes(0) No(0)
• A*B/LCM=4
  
• 10 years agoHelpfull: Yes(0) No(0)
• LCM*HCF(of any two number)=Product of two no.s
  25X=100
  x=4
• 9 years agoHelpfull: Yes(0) No(0)
• lcm*hcf=n1*n2
  25*hcf=100
  hcf=100/25
  hcf=4
