Question

The HCF and LCM of two numbers are 13 and 1989
respectively. If one number is 117 find the other.
EXPLAIN IT PROPERLY PLEASE​

Answer 1

Answer:

I believe that the product of the HCF and LCM of two numbers is equal to the product of the two numbers.

13 x 1989 = 25857

25857 / 117 = 221 is the other.

I would check to see if it works.

117 = 3 x 3 x 13

221 = 13 x 17

HCF = 13

LCM = 3 x 3 x 13 x 17 = 1989
