Question

Calculate the ratio between the LCM and HCF of 5,15 and 20

Answer 1

Answer:

LCM :- 5 , 15, 20

==> 5*2*2*3 ==> 60

HCF :- 5,15,20

      5 = 1*5

     15 = 1*5*3

     20 = 1*5*2*2

S0, HCF = 5

RATIO OF LCM : HCF ==> 60:5 ==> 12:1

Answer 2

LCM:
5=5*1
15=5*3
20=5*2*2
LCM=5*3*4=60
HCF=5
LCM/HCF=60/5=12:1
