Given numbers are 128, 696, 961, 398

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

Apply this formula for all numbers.

Step1:

LCM(128, 696) = 11136

GCD(128, 696) = ( 128 x 696 ) / 11136

= 128 / 696

= 128

Step2:

LCM(8, 961) = 7688

GCD(8, 961) = ( 8 x 961 ) / 7688

= 8 / 961

= 8

Step3:

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

= 1 / 398

= 1

So, Greatest Common Divisor of 128, 696, 961, 398 is 1
