Question

the HCF of two numbers is 4 and their LCM is 400.how many pairs of values can the number assume​

Answer 1

Step-by-step explanation:

Since HCF of the numbers is 4. So, two numbers are multiplies of 4. Let the numbers be 4x and 4y.

$4x \times 4y = 4 \times 100$

$xy = 100$

$x = 25 \: y = 4 \: or \: x \: = 100 \: y \: = 1$

So, the possible number of pairs is 2.
