GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(309, 128) = 39552

GCD(309, 128) = ( 309 x 128 ) / 39552

= 309 / 128

= 309

Step2:

LCM(1, 791) = 791

GCD(1, 791) = ( 1 x 791 ) / 791

= 1 / 791

= 1

So, Greatest Common Divisor of 309, 128, 791 is 1
