Question

the ratio of the LCM and HCF of 2, 10 and 20 is​

Answer 1

To find the ratio of LCM and HCF, we need to find the factors of 2,10 and 20

Factors of 2:

2=2 X 1

Factors of 10:

10=2 X 5 X 1

Factors of 20:

20=2 X 2 X 5 X 1

Now,

LCM=2*2*5=20

HCF=2

Using this we can find the ratio of LCM and HCF which is given as 20:2=10:1
