Question

product of two numbers is 324.what will be the hcf?
​

Answer 1

Step-by-step explanation:

324=2*2*3*3*3*3

HCF=2*3=6 ;LCM =54 TRUE

HCF=4 ; LCM =81 NOT TRUE (HCF=1)

HCF=18 ; LCM =18 TRUE

HCF=2 ; LCM =162 TRUE.

HCF=3 ; LCM=198 TRUE

HCF=9 ; LCM =36 TRUE

HCF= 12 ;LCM= 27 NOT TRUE (HCF=3)

HCF=1 ; LCM =324 TRUE

So all the above groups are TRUE except(4,81)&(12,27) ANSWER
