Given numbers are 128, 809, 391, 244

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

Apply this formula for all numbers.

Step1:

LCM(128, 809) = 103552

GCD(128, 809) = ( 128 x 809 ) / 103552

= 128 / 809

= 128

Step2:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

Step3:

LCM(1, 244) = 244

GCD(1, 244) = ( 1 x 244 ) / 244

= 1 / 244

= 1

So, Greatest Common Divisor of 128, 809, 391, 244 is 1
