Answer:

The numbers are 32 , 48

Step-by-step explanation:

Average = 40

Sum of two numbers = 40 * 2 = 80

Let one number =x

Other number = 80 - x

Product of two numbers = GCD * LCM

x*(80-x) = 16*96

80x - x² = 1536

1536 + x² - 80x = 0

x² - 80x + 1536 = 0

x² - 48x - 32x + (-32) * (-48) = 0

x (x -48x) -32 (x -48) =0

(x - 48) ( x - 32) = 0

x - 48 = 0    ; x - 32 = 0

x = 48          ; x = 32
