6 the LCM of two number is 19 point if the two number are 63 and 117 find the HCF
$\cot(?)$
​

Answer 1

5) HCF = 12

LCM = 72

WE KNOW, PRODUCT OF TWO NO. S IS EQUAL TO THE MULTIPLICATION OF THEIR HCF AND LCM.

SO, THE PRODUCT OF THE TWO NO. IS = 12×72

864

6)

QUESTION IS WRONG

THEIR LCM CAN NOT BE 19

63 ,117

THEIR HCF IS 9

AND LCM IS 819

Hope it Helps
