Question

Hcf and lcm of 2 integers are 12 and 720 respectively . How may be the number of pairs and which are the numbers?

Answer 1

Answer:

Step-by-step explanation:

HCF = 12

LCM = 720

Product of two numbers = 720 x 12

                                         = 8640

The number of pairs are:

   360 x 24,  180 x 48,  90 x 96,  45 x 192, 15 x 576, 5 x 1728,

    2 x 4320, 3 x 2880, 4 x 2160, 6 x 1440, 8 x 1080, 9 x 960,

  10 x 864, 720 x 12, etc.,
